Light pipe
* are a trendy and economical alternative to skylights
  - optical elements that transfer light from a source to a lighting task
* take both direct and diffused sunlight and guide it in a reflective tube to a diffuser.

Panpipe
* are also common in music, as are conch shells, which double as bush telephones
  - musical instruments
  - pipes
  - rather simple to play
* is where it's at.

Perforated pipe
* allows water to enter or exit through small openings along a length of a pipe.
* is used so that water can drain into the well from the surrounding saturated soils.
* length of casing that has holes or slots drilled or cut into the pipe.

Pipeline
* are a law-enforcement problem within countries
  - buffers
  - made of metal
* are the different paths in a processor that process instruction simultaneously
  - most economical and safest means of transporting oil and gas over long distances
  - principal method of natural gas transportation
  - safest and cheapest way to move large quantities of petroleum across land
* big wave that turns into a small wave.
* move oil long distances by pumping.
* prevent loss of water by evaporation and seepage.
* promote use of natural gas, which burns cleaner than oil or coal.
* transport crude oil to refineries, a process that takes ten days on average.
  * A 'pipeline' long tube, that is used to transport liquids or gases over long distances. Pipelines are made of metal. While the transport of liquids and gases is common, some pipelines are used to transport coal or iron ore, which are mixed with mud. Such pipelines are sometimes called slurry pipelines. Even though a pipeline is very expensive to build, it often more economical form of transport that the transport by road.

Underground pipeline
* bring natural gas to cities and towns.
* can easily move petroleum and natural gas to market.

Plastic pipe
* Most plastic pipes contain matter
  - particulate matter
* can melt if excess boiling water is used.
* is lighter and less expensive than stainless pipe.
* solidifies slowly when extruded.
* widely used material because it is light weight and flexible.

Scupper
* are drains.
* create an exit for water through a parapet wall or an elevated edge.
* drains allow direct discharge of runoff into surface waters below the bridge deck.

Standpipe
* are pipes.
* are the vertical piping that supply water to fight fires on every floor of a high-rise
  - water to individual floors in a high rise

Syrinx
* Most syringes come pre-packaged and contain a small amount of heparin , to prevent coagulation.
* Some syringes come with caps to prevent medicine from leaking out
  - now have shorter needles which many people find to be more comfortable
* Syringes allow scientists to pull samples for analysis during growth sequences.
* Syringes are also convenient for storing a dose
  - illegal, so shooting galleries flourish where needles are shared by dozens of people
  - mass-produced
  - never to be disposed of in regular waste streams
* Syringes come with a variety of sizes, tips, and plunger types
  - either a centrally or eccentrically located hub
  - have removable needles with flexible tips
  - require no stirring or shaking just warm to room temperature
* Syringes tend to be expensive and wear out quickly
  - stick and give bursts of vacuum
  - work because of a thing called pressure
* are part of birds
  - structures
* is the pipes of Pan.

Plastic syrinx
* All plastic syringes are latex free, contain no rubber, no silicone, and are completely inert.
* Plastic syringes contain latex at the end of the plunger.

Vent pipe
* are located in roofs.
* have gaps, leaks, spaces or are rusted through.
