## Ice

(H2O) Ice is clean water frozen into a Solid state.

### Properties

 Ice, Generic Buildable, Solid, Liquefiable

**Ice** is a water source found in the Frozen Biome.

## Usage

A storage of Ice placed in Water pool can help cooling the water.

Ice Block requires Ice to build. It has the highest base decoration value (+20) in the game, together with Marble Block and Metal Block. It will melt in warm environments so better build it in Frozen Biome only.

Ice-E Fan can use Ice to cool the environment. The consumed Ice is melted into bottled Water.

## Production

Cooling Water below its freezing point will turn it into Ice. A water tile less than or equal to 800 kg will turn into ice debris, while a water tile greater than 800 kg will turn into an ice tile.

Cooling Salt Water below its freezing point will turn it into Ice (77% mass) and Brine (23% mass).

Ice Maker can make Ice from Water.

 It can be harvested on rocket missions to renewable Space POIs:

* In Exploded Ice Giants at a rate of 324 – 972 kg per cycle.
* In Frozen Ore Asteroid Fields at a rate of 148 – 443.9 kg per cycle.
* In Ice Asteroid Fields at a rate of 135 – 405 kg per cycle.
* In Oxygen Rich Asteroid Fields at a rate of 60 – 200 kg per cycle.
* In Interstellar Oceans at a rate of 37.5 – 125 kg per cycle.

## Tips

* Mining anything, including ice, will destroy 50% of the original mass. Melting it instead will keep all the mass and double the amount of precious water received but can not be moved as easily.
* Ice is generally encountered in biomes with starting temperatures well below the freezing point of pure water. By piping in heat so as to locally melt ice, the water runoff will often re-freeze as dupe-portable ice. If the ice is melted with salt water, it is often the case that the temperature exchange will turn the salt water into brine+ice.
* Constructing a Tempshift Plate out of Ice will not be affected by the 15°C lower limit of building temperatures. On the other hand, you can only use 20% of the Ice heat capacity that way, as only 20% of buildings mass is considered for heat calculations.
Manual Radbolt Generator

*This article is related to DLC content of Spaced Out.*

Refines radioactive ores to generate Radbolts.
Emits generated Radbolts in the direction of your choosing.

Radbolts are necessary for producing Materials Science Research.

The Manual Radbolt Generator is the most basic way of generating Radbolts needed for advanced research in Spaced Out. Like the Radbolt Reflector, bolts can be configured to emit in eight directions around its output port.

Unlike the Radbolt Generator, it does not require Power to operate, relying instead on a supply of fuel and Duplicant operation.

The generator fires a Radbolt projectile as soon as the progress bar is finished.

## List of Recipes

 Enriched Uranium to Radbolts and Depleted Uranium | 1kg Enriched Uranium | 0.8kg Depleted Uranium | 25

## Notes

* Keep in mind that refining the Uranium Ore with Uranium Centrifuge does not increase the amount of Radbolts gained per 1kg of Uranium Ore. However, it does reduce the mass loss from 50% to 4% , at the additional Power cost and processing time.
```
100kg Uranium Ore -> 500 Radbolts + 50kg Depleted Uranium
Total: 500 Radbolts and 50kg of Depleted Uranium

100kg Uranium Ore -> 20kg Enriched Uranium + 80kg Depleted Uranium
20kg Enriched Uranium -> 500 Radbolts + 16kg Depleted Uranium
Total: 500 Radbolts and 96kg of Depleted Uranium

```

## Jet Suit

Supplies Duplicants with Oxygen in toxic and low breathability environments.
Allows Duplicant flight.

### Effects

Insulation +50
Athletics -6
Insulation Thickness +20 cm
Excavation +10
Scalding Threshold +726.9 °C
Oxygen Tank (75 kg)
Petroleum Tank (25 kg)

### Cost

200 kg Steel
25 kg Petroleum

### Research

Jetpacks

**Jet Suit** can be produced in the Exosuit Forge, they are more advanced version of Atmo Suit fitted with jetpacks. When jetpack is active the suit burns 100 g/s of Petroleum, and exhausts 300 g/s of Carbon Dioxide. Duplicants are smart enough to pay attention to their fuel reserves and will retreat to the dock if Petroleum runs low.

Jet Suit have internal reserves of Oxygen and Petroleum, and can be refilled inside powered Jet Suit Dock. They are quite bulky and provide a significant Athletics penalty if the dupe lacks the Exosuit Training skill.

Jet suits still may overheat in high temperatures and bother the wearer with *Toasty Surrounding*, such as when submerged in Crude Oil above 105 °С for a while, but health-damaging scalding effects will only happen in extremely hot environments, such as when submerged in magma.

Like all clothing it can be manually assigned to Duplicants. However, once suit's Oxygen supply is depleted they will start suffocating and might die. The dupes can make a mess in their suit, causing significant Stress. The germy Polluted Water from inside the suit will be dropped on the floor when the dupe unequips the suit.

## Tips

* Jet Suit can have a heavy impact on FPS, because of extension of pathfinding trees. It's recommended to use them only in enclosed sections.
	+ In Space Biome, when trying to enclose a region, dups could fly through non-building zone if there isn't any regolith blocking the path.
* Their flying speed is extremely slow, comparable to an upwards climb on a Fire Pole. This severely limits their utility outside of highly specialised tasks like rocket servicing.

A **mechanical filter** is a type of designs allowing to filter out gases and liquids via their mechanical behavior instead of specialized buildings. Those patterns tend to work passively, rely on no power at all, but their efficiency might vary depending on situation.

## Utilizing layering

Both gases and liquids tend to naturally sort themselves out into layers based on their densities and pressures if left undisturbed, which allows for building of low maintenance catchment and overflow structures.

The most basic example of that is Carbon Dioxide pits used to store food, which fill themselves with natural output of duplicants or any Carbon Dioxide falling from the upper levels. It can be extended to "industrial" pit, where generators and machinery are placed below the base habitation level, which provides passive heat insulation via natural properties of denser gasses.

It is mirrored by hydrogen catchers, built inside SPOMs and incorporated into upper levels of bases, which allow to use only one occasionally run pump to collect any and all incoming hydrogen.

Liquid-related design are trickier, but still possible, since clear water always sort itself over polluted and liquids tend to stick inside narrow, one-tile passages. But mostly it is used as a base for Liquid Airlocks and gas separation.

Tile-based mechanical filters demand non-localized approach and stable conditions or they can be overwhelmed by minutia change, for example fluctuations in oxygen pressure might lead to chlorine and CO2 escaping from upper-layer pits into lower layers, which in turn makes it even less breathable there.

## Inside pipes

Mechanical filters inside pipes tend to utilize their "packet" nature by pre-seeding and constantly looping tiny packets of desirable material, which blocks passage for any other materials.

Pipe-based mechanical filters might limit overall pipe-throughput and are vulnerable to clogging, if designed carelessly.

## Ice Maker

Converts Water into Ice.

Ice makers can be used as a small renewable source of ice.

### Storage Capacity

Water: 30 kg
Ice: 150+ kg

### Auto In

**Green**: Enable
**Red**: Disable

## Materials

### Metal Ore

400 kg

**Ice Maker** is a machine that freezes water into ice. It will relocate the heat energy from the water until the water is -20 °C ice. The ice maker heats up significantly but the total heat output is negative 3700 DTU/second. The DTU deleted per second does not change depending on the input water temperature though hotter water will take longer to become ice.

It will start new production cycles as long as there is less than 150 kg of ice in storage for a theoretical storage capacity of 179.9 kg.

History: Before "the Automation Update" several years ago, the Ice Maker used to have no overheat temperature, so it could be used to achieve high temperatures. However, this has been addressed in a patch for the Automation Update, and it now has an overheat temperature.

### Heat deletion:

It cools the 30 kg of stored water at a rate of around 0.16 K/s and consumes 60 W. This translates to a cooling efficiency of 333.33 DTU/W. In comparison, the Thermo Aquatuner would cool 10 kg of water at 14 K/s and consume 1200 W, an efficiency of 487.43 DTU/W. Note that the Ice maker does not respect the usual hysteresis of water's freezing temperature: the water it contains will turn to ice at exactly 0.6 °C.

The Ice Maker cools 30kg of Water at a rate of 0,16K/s.

We calculate the delete heat as: SHC \* ΔT \* Mass : 4,179 (DTU/g)/C \* -0,16C \* 30kg = 20,06kDTU.

The Ice Maker only produces +16k DTU/s this means we delete 4kDTU/s while it's running.

This can be helpful early game. Especially since the heat can be removed from specific areas easily by moving the ice into the vicinity and it's an easy way to turn duplicant labor into heat deletion.

## History

* **AP-419840**: **Ice Maker** is now overheatable like other production buildings

## Lab Window

A lab window. Formerly a portal to the outside world.

### Material

5 kg  Glass

The **Lab Window** is a Building which can only be found inside the Somnium Synthesizer story trait point of interest, which cannot be built. It is a type of Background Building, similar to Drywall.

It is essentially a window variation of the Lab Wall, and thus is also similar to the Window; although the Lab Window takes up the same area (2x3 cells) as the Window (1x6 cells), the latter contains 5x the mass and provides 2.5x the Decor.

## Trivia

* It is difficult to tell, since the background textures of the biomes that the Somnium Synthesizer point of interest can spawn in are relatively smooth and textureless, but the Lab Window is in fact subtly transparent (albeit less so than the Window).

Guide/Gym

**Gyms** are part of a colony in which Duplicants can level up their Category:Attributes Points.

## General

Gyms are often closed off sections of the base where training Duplicant are not allowed to leave, only have one possible **reoccurring** errand to run with a dedicated Barracks, Latrine and Mess Hall, where their Food gets delivered either by automation or by other Duplicants.

Duplicants should first be given any possible Research Skills they can afford with their Skill Points (freshly printed Duplicants always start out with one), since Science increases the speed at which Attribute Points are gained. Afterwards, they can be skill scrubbed.

Attribute points are gained based on how long a Duplicant works on a task, not by how difficult it is. Therefore, for tasks that are not easily made reoccurring, the Duplicant can be intentionally debuffed with disease. This slows down their work speed, but effectively increases the amount of attribute points they gain for a single task, after all, they have to work longer on them.

## Athletics and Machinery

Athletics and Machinery are both gained by operating a Manual Generator. By hooking up a single power user without a battery (usually a Ceiling Light overhead), this power user will be in constant need of power, and therefore have an infinite errand.

## Incubator

Incubates Critter eggs until ready to hatch.
Assigned Duplicants must possess the Critter Wrangling trait.

Incubators can maintain the ideal internal conditions for several species of critter egg.

### Requires

Critter Eggs
Duplicant operation
Critter Ranching I skill

### Auto In

**Green**: Enable
**Red**: Disable

## Materials

### Refined Metal

200 kg

An **Incubator** incubates the eggs of critters until they are ready to hatch. Eggs inside an Incubator can be lullabied by a Duplicant rancher, giving the egg a buff for one cycle that increases the incubation speed by up to 400% (5 times faster). For example, Pacu naturally take 5 cycles to hatch at 20% incubation per cycle, and the "lullabied" status adds 80% to this rate, guaranteeing the Pacu egg to hatch in 1 cycle.

Once the critter hatches inside the incubator, a duplicant will take it to a Critter Drop-Off. Critters can be also removed from the incubator by pressing the "Remove" button. If left inside the incubator (due to low priority or no critter drop offs with space available), the critter will leave incubator on their own when they turn into an adult.

Assigned duplicants must have the Critter Ranching I skill.

## Automation

A disabled incubator will not consume any power and will be unable to be lullabied by a Duplicant. Duplicants will still bring an egg to a disabled incubator.

However, if an egg is lullabied and the incubator subsequently left unpowered, the egg will retain the increased incubation rate until the effect wears off. This can be combined with a clock sensor to the run the incubators briefly during part of the day and setting their priority high so that eggs receive the increased incubation rate without the increased power consumption.

Guide/Door Pump

A door pump is an automated machine consisting of at least 3 Mechanized Airlocks, some automation or similar way of timing, and liquids or gases to move.

## Theory

When an airlock opens, it creates a Vacuum where it was, therefore sucking in any nearby gasses or liquids, and when it closes, it will push the elements inside of it out.

A Door Pump chains multiple Doors together to transport Elements from one side to another, usually used to keep a Geyser from overpressurizing. See Geyser Taming for more info.

Cycle:

* The first two doors may open at the same time. Sucking the element in.
* The fist door closes, locking the element inside the center door.
* The last door opens, letting the element out.
* The center and last door close in succession.

## Basic Design

A Timer Sensor can give an impuls, and each door can be put behind a **BUFFER** and **FILTER Gate**.

In the simplest terms, the **BUFFER Gate** prolongs that input until the door needs to close, and the **FILTER Gate** cuts the signal off to when the door needs to open.

### Improved Design

This design immediately uses the Timer Sensor more efficiently, removing the necessity of half the gates. Furthermore only activates it if there is enough Gas Pressure in the Geyser Room, which stops it from wasting power. However, The Design can also be used without needing to power the doors, as long as the sensor timing is adjusted accordingly.

Sensor Timing
8 Seconds Off
 Middle Door (Buffer Sensor)
 Last Door (Buffer Sensor)
 Last Door (Filter Sensor)

## Other Designs

### Liquid-controlled pump

An alternate design of pump is the liquid-controlled pump. It looks like this:

This type of door pump does the same thing as an automation-controlled one. It consists of 3 packets of liquid moving through an infinite loop, triggering pipe sensors as they move.

This could be coupled with a liquid shutoff on the bottom left of the pipe circuit to turn the pump on and off, however you must make sure that the packets of liquid are all maximum size, or they will combine when the shutoff turns on.

## Liquid Valve

Controls the Liquid volume permitted through Pipes.

Valves control the amount of liquid that moves through pipes, preventing waste.

### Piping

Input: Liquid Intake
Output: Liquid Output

## Materials

### Metal Ore

200 kg

**Liquid Valve** allows the player to control or stop the contents of a Liquid Pipe. Best to use after branching. Maintains pressure in an empty pipe before deconstructing it. Because it allows liquid flow only one way, it can also be used to give the game a hint what flow direction the liquid has when the pipe grid gets more complicated.

## Flow

The Liquid Valve has a flow setting, ranging from 0 g/s to 10,000 g/s. This setting is the upper limit of the output liquid flow. For example, if the setting is set to 5 kg/s and input flow is 10 kg/s, the output flow is limited to 5 kg/s and excess liquid is blocked. If the setting is set to 5 kg/s and input flow is 3 kg/s, the output flow is 3 kg/s.

A valid flow setting is rounded the first decimal place and has the following limits:

* the minimum flow is 0 g/s;
* the maximum flow is 10,000 g/s;
* the minimum, nonzero flow is 0.1 g/s (100 mg/s).

Switching the volume setting of Liquid Valve requires Duplicant operation, and takes some time.

**Heat Stroke** is a temporary status appearing when Duplicants get overheated. When it is applied Duplicant will begin to take health damage until their body temperature drops. Additionally, athletics penalty from health damage is also applied until the injury is healed.

Duplicants will try to leave overheated location, unless they have active errands in there.

The typical sources of Heat Stroke are Geysers, hot bodies of water and overheating machinery. Oil Biome is also usually hot enough to quickly induce Heat Stroke, and Volcanic Biome is straight up lethal.

The opposite of Heat Stroke is Hypothermia.

## Penalties

* Science -5
* Machinery -5
* Cuisine -5
* Construction -5

Duration: 180 seconds (0.3 cycle)

## Tips

* Avoid sending dupes into hot environments without proper equipment (Atmo Suit/Jet Suit).
* Set up your Triage Cots to low thresholds to quickly remove athletics penalty.
* The Regenerative trait will make duplicant regenerate health, which will remove the athletics penalty after some time (20hp/cycle).

## Leaky Oil Fissure

A fissure that periodically erupts with boiling Crude Oil.

### Deconstructible

No

**Leaky Oil Fissure** is a renewable source of Crude Oil, which can be found in Caustic Biomes. It is **not** guaranteed to spawn.

It should not be confused with Oil Reservoirs, which are guaranteed to spawn naturally in the Oil Biome, and need an Oil Well to produce oil. In contrast, Leaky Oil Fissure produces Crude Oil on its own and doesn't need Water or Power to do so.

## Taming

The oil produced by a Leaky Oil Fissure is too hot to be handled by Steel machinery, so some cooling is necessary if handling it using pre-space age materials. A single self-cooling Steam Turbine is sufficient to cool up to 875 g/s of oil, much more than the typical fissure produces, to 130 °C, well within the safe operating range for self-cooling.

With access to space-age materials, it may be preferable to simply build a Thermium Thermo Aquatuner directly adjacent to the fissure and boil the oil directly to Sour Gas, bypassing liquid infrastructure altogether.

Its good to note that Leaky Oil Fissures will never go Idle but they do have a "dormant" period which acts more like an idle period as it stops erupting for a very short amount of time; this dormancy period lasts 40 s - 400 s, averaging 220 seconds (less than half of one cycle).

## Tips

Crude Oil emitted by the fissure is a very good feedstock for a Petroleum Boiler, as it only needs to be heated by about 76°C to turn into Petroleum. In contrast, Crude Oil produced by an Oil Well is "only" 90°C or hotter, meaning it has to be heated by about 313°C to turn into Petroleum in the worst case.

However, be warned that mixing feedstock to the common counterflow boiler design may result in pipes bursting or pump damage due to its high temperature - not only is it hot enough to damage Steel machinery itself, it will not provide adequate cooling for the output Petroleum if it is built to expect lower-temperature Crude Oil (such as from an Oil Well).

One of several Attributes a Duplicant possesses. It determines the speed at which actions such as operating machinery and fabricating items and resources are completed. Affected errands include: Space Mission, Generate Power, Tinker, Operational Supply, Use Fan, Train, Power Supply, Depressurizing an Oil Well, Fabricate, and Fabrication Supply.

 For each level of this attribute, the duplicant gets:
* +10% tinkering and repairing speed
* +2.5% engie's tune-up duration
* Performing successful space missions
* Using Manual Generators
* Using microchips to soup-up power supplies
* Operating Ice-E Fans
* Improved Tinkering I (+2)
* Electrical Engineering (+2)
* Mechatronics Engineering (+2)
* Early Bird (+2, but only in the morning)
 * Heat Stroke (-5)
* Hypothermia (-5)
* The Spores (-10)

## Trivia

Before the Launch Update, this attributes name was Tinkering.

## Manual Airlock

Blocks Liquid and Gas flow, maintaining pressure between areas.
Sets Duplicant Access Permissions for area restriction.

Wild Critters cannot pass through doors.
Airlocks can quarter off dangerous areas and prevent gases from seeping into the colony.

## Materials

### Metal Ore

200 kg

**Manual Airlock** creates an airtight seal that maintains atmosphere and pressure between areas.

The Manual Airlock is ~1 second faster than unpowered Mechanized Airlock, but noticeably slower than powered or Pneumatic Door.

Manual Airlock and Mechanized Airlock can prevent the gases leaking into space when Duplicants access Space Biome.

## Tips

* This airlock, and all other doors can be built horizontally by rotating the blueprint, default button is the letter: O
* Manual and Mechanized Airlocks count as floor tiles when closed, but not when open. Unlike Pneumatic Doors, Building atop them still works.
* Manual Airlocks and Mechanized Airlocks don't get damaged by high liquid pressure, which makes them perfect for building large liquid tanks or liquid compressors.
* Despite the name, the Airlock is not a fully-functional airlock, but rather an airtight door. Gases and liquids pass through it when opened. A proper airlock can be constructed by combing two Airlocks and some pumps.
* Manual Airlocks can be constructed from Uranium Ore. This will result in a door that emits a small amount of Radiation (29 rads at the door itself, radiating 2 tiles away at 21 and 6.6 rads, respectively). This may clear very low levels of germ infestations, though a Mechanized Airlock may be better suited for desinfection purposes. Notice also that the door only emits radiation when closed, not when open.

## Bugs

* Deconstructing a vertical manual airlock surrounded by tiles on the left, right and bottom will result in a natural tile, of the same material as the door, being created on the bottom block.
	+ The mass of tile will be half the mass of the door.

## Meat

Uncooked meat from a very dead Critter. Yum!

### Source

Critters

**Meat** is recommended to be cooked into a Barbeque in an Electric Grill as it provides 400 more calories per kg and has better quality than Meat. Barbeque also serves as an ingredient in even better meals made in a Gas Range.

## Recipes

Inside the Electric Grill, it can be cooked into

**Hardness** determines how hard it is to dig out a tile and how much the tile can withstand pressure primarily from Liquids.

Especially Tiles out of Sandstone are unsuitable to hold large amounts of water.

Very Firm materials like Granite require skilled dupes to be mined. Nearly Impenetrable materials like Abyssalite need even further training.

## Liceloaf

Meal Lice compacted into a dense, immobile loaf.

## Ingredients

### Water

50 kg

**Liceloaf** can spread Food Poisoning if Water used to create it was contaminated with germs.

## Tips

Making Liceloaf effectively converts 50 kg of water into 500 kcal of food, which is somewhat less efficient than Bristle Blossom farming, which can convert 50 kg of water into 833.3 kcal of Gristle Berry. If water is in a limited supply and Dirt is plentiful, the Meal Lice should probably be eaten raw.

* The process to make Liceloaf is also rather long - but it does not require the Cooking skill.

## Sommaire

Ce Guide à l'intention d'empêcher vos Duplicants de suffoquer. Il comparera les moyens de fournir de l'Oxygen/fr à votre colonie. Il expliquera aussi comment controller le gaz CO~~2~~ produit par la réspiration et par quelques structures.

## Pratique a savoir

* Un Duplicant consomme approximativement 100 g d'Oxygèn par seconde.
* Les Duplicants avec le trait Mouth Breather on besoin de double l'oxygèn, donc 200 g/s.
* Les Duplicants aves le trait Diver's Lungs on besoin de 25 g par seconde de moins, donc 75 g/s.

## Le Début

Quand vos Duplicants apparaissent dans votre colonie Cycle 1, ils peuvent seulement respirer ce qui est fourni, ce qui est surtout une petite réserve d'Oxylite dans le Biome où vous commences. Elle va être épuisée dans seulement quelques cycles, et il n'y as aucune façon de s'y fier comme solution permanente. Mais n'inquiètez vous pas, puisque vous pouvez construire un Oxygen Diffuser dès le début, et vous pouvez rechercher quelques structures additionnelles qui replissent votre oxygène plus efficacement. Faites fonctionner votre Research Station!

## Insulated Liquid Pipe

Carries Liquid with minimal change in Temperature.
Can be run through wall and floor tile.

Pipe insulation prevents liquid contents from siginificantly changing temperature in transit.

## Materials

### Plumbable

400 kg

**Insulated Liquid Pipe** is a type of Liquid Pipe that greatly slows down the heat exchange between the liquid content and the environment. It costs 4 times mass compared to regular Liquid Pipes.

## Heat Exchange

The thermal conductivity of the Insulated Liquid Pipe is reduced to 3.125% of the thermal conductivity of the building material. Furthermore, when calculating the heat exchange between the liquid content and the Insulated Liquid Pipe, it uses the lower value of thermal conductivity (which is very likely the one of the insulated pipe) instead of the average value when calculating for regular Liquid Pipes. The 400% mass also means less temperature change for the same amount of DTU exchanged, which again slows down the heat transfer between insulated pipe and the surrounding tile.

Igneous Rock and Ceramic are the best materials to use. You may want to save Insulation for the most extreme scenarios.

## Usage

* Glass Forge outputs Molten Glass which may quickly freeze into solid Glass and damage regular liquid pipes. Use Insulated Liquid Pipe to prevent the pipe damage.
* When cooling a liquid with Thermo Aquatuner, the input/output liquid content may get re-heated by the surrounding hot liquid. Use Insulated Liquid Pipe to keep the liquid content in low temperature.

## Tips

* To save more Insulation, use Liquid Bridge which does not heat exchange with contents.

## Lumber

Wood harvested from an Arbor Tree or Oakshell.

### Properties

 Wood

**Lumber** is an Industrial Ingredient item harvested from Arbor Trees or by crushing the Molts of Oakshells.

## Usage

* It is used to make items such as:
Sauna
Hot Tub
* Wood Burner can burn Lumber to generate Power.
1.2 kg/s Lumber = 300 W Power + 170 g/s Carbon Dioxide.
* Ethanol Distiller can produce Ethanol from Lumber.
1 kg/s Lumber = 500 g/s Ethanol + 333.33 g/s Polluted Dirt + 166.67 g/s Carbon Dioxide.

## Production

* Arbor Trees are a renewable source of Lumber.
* Rock Crusher produces Lumber from Oakshell Molt:
	+ 1 unit small Oakshell Molt = 10 kg Lumber
	+ 1 unit (regular) Oakshell Molt = 100 kg Lumber.

## Notes

* Lumber is an item made of Genetic Ooze.
* Lumber is sometimes referred to with **kg** and sometimes with **units**.

## Lettuce

Crunchy, slightly salty leaves from a Waterweed plant.

### Source

Waterweed

**Lettuce** is a food item grown from Waterweed in 12 kg amounts which is equivalent to 4800 kcal. It has a Food Quality of Terrible (0).

## Recipes

Inside the Gas Range, it can be cooked into

* 1600 kcal per Mushroom Wrap recipe
* 400 kcal per Frost Burger recipe

## Tips

* 12 Frost Burger orders can be made for each growth cycle of Waterweed. This means if you choose to feed your Duplicants only Frost Burgers you will need ~0.166(domestic)/~0.666(wild) Waterweed plants per duplicant to supply the Lettuce.
* 3 Mushroom Wraps can be made for each growth cycle of Waterweed. This means if you choose to feed your Duplicants only Mushroom Wraps you will need ~0.833(domestic)/~3.333(wild) Waterweed plants per duplicant to supply the Lettuce.

**Hot Tub** is used during downtime to improve a duplicants' morale. A dupe will spend 90 seconds (~4 schedule blocks) in the hot tub. Up to 4 dupes are able to use the Hot Tub at the same time. Despite being a recreational building, it does not need to be in a recreational room.

Hot tub consumes bleach stone and cycles water, expelling it when the temperature drops below 37.7 °C. Any other liquids will damage the building and spill out.

## Tips

* The Hot Tub requires precise water temperature input and produces a large amount of heat (5KTDU/s).
	+ Water must be kept heated (at least 37 degrees) going into the Hot Tub but the surroundings must be cooled as the unit will not function if above 37.7 degrees.
	+ Building material matters more with the Hot Tub than any other device. Steel raises the overheat of the Hot Tub to 237.7C making it able to handle much hotter water.

## History

* **RP-379337**: Introduced.
* **RP-380770**: Updated Hot Tub artwork.
