U-locks are very difficult to open by hammering or using force, but they are weakened and become brittle when cooled by air spray, meaning that they can be smashed open. Buy compressed or canned air at home improvement stores or online. Canned air contains the compressed chemical difluoroethane, which will cool the lock to around -13 degrees F (-25 degrees C). If your U-lock is locked but not connected to anything, breaking it will be easy. If the U-lock is locked around a bicycle or a door handle, it will a little more difficult to open, but it will still be doable. Position the U-lock so that the bar of the U-lock is lying flat on the ground or is against a stable surface like a door or the bar of the bike rack. Hold the can of air spray about a foot away from the keyhole. Then hold down the trigger of the canned air and spray it directly at the keyhole. Spray continuously for about 30 seconds. You will notice the bar becoming white as the chemical reacts with the surface of the U-lock and chills it. Be sure to aim the spray radius at the keyhole, where you will focusing your hammering. After about 30 seconds, the bar of the U-lock will have been chilled and should be brittle enough to break. Use your non-dominant hand to hold the U-lock by its loop against the ground or the surface that you positioned it against. Pick up the hammer in your dominant hand and begin to hammer against the keyhole. Keep your fingers away from the place that you are hammering. Also try to keep the U-lock stable and in position as you hammer. Don't be alarmed as you see the white powder on the U-lock come off in a mist as you begin to hammer. Keep hammering against the keyhole area of the U-lock. You may have to hammer for 30 seconds or so until a piece breaks off of the bar, after which breaking it will become much easier. Focus your hammering against the broken area of the lock. More sections will come off, until the bar breaks completely and separates from one or both sides of the U. Be patient, as it may take several minutes of hammering to break the U-lock. Dispose of the remains of the lock when you are finished.

One-sentence summary -- Purchase canned air spray. Position the U-lock. Spray the canned air at the keyhole of the U-lock. Spray for about 30 seconds. Begin hammering against the keyhole. Hammer until the U-lock breaks.

Q: If you are reupholstering an existing bench, you will need to unscrew the legs and reattach them later. If you are reupholstering a bench, you will also need to remove staples at the back of the base with needle nosed pliers. Then, remove the fabric, batting, and foam so that you can replace them. It is a good idea to replace them unless they are relatively new. Keep your piece of fabric to use as a template for your fabric bench cover. If you are creating a bench from scratch, you can customize it to the space you want to fill. Measure the area in inches. Ask the store to cut it to the exact size that you measured. Your foam core should be at least three inches (7.5cm) thick to assure comfort. Purchase one and a half times the size in upholstery or outdoor fabric. Just as home improvement stores will cut plywood for little to no cost, large fabric stores can cut foam core to size. Use an electric knife to cut foam core at home. It is easiest to upholster a bench if you are able to slide the fabric and batting along a smooth surface. Practice attaching them before you start upholstering to ensure they work for your piece of furniture. You will need a drill and screws for this process.
A: Choose to either reupholster an existing bench or make a new one. Measure an existing frame or decide how large you want your bench to be. Purchase a piece of 1/2 inch to 3/4 inch plywood from a home improvement or lumber store. Buy thick foam core and in a size that is greater than or equal to the size of your piece of wood. Clear a large workspace or table. Drill holes into the corners for the legs.

Article: Death caps are highly poisonous mushrooms with 6 inches (15cm) wide caps. These caps might be yellow, white, brownish, or greenish in color, and are generally sticky to the touch. Death cap mushrooms have white gills, and they grow on 5 inch (13 cm) tall stalks. The death cap is blamed for the most mushroom poisonings in the world. These mushrooms generally grow from September to November in the US and Europe. Destroying angels are known for a wide cap, medium-sized stalk, and frilly gills. Destroying angel caps can be either pure white, or white at the edge and light yellow, light pink, or pale tan at the center. Destroying angels typically grow near the roots of trees or shrubs. They are most common in the summer and fall. They are typically about 25 inches (5.112.7cm) across. Death caps, destroying angels, and many other harmful mushrooms belong to the Amanita family of mushrooms. Although you may pass over some potentially edible mushroom, you can avoid the whole family by staying away from mushrooms with their particular characteristics. These include: White gills A skirt or ring on the stem A bulbous or sack-like base called a volva As a good rule of thumb, never consume a mushroom until you have positively identified that species at least 3 times. Any time you are unsure about a mushroom, ask for advice from an expect.
Question: What is a summary of what this article is about?
Identify death caps by their large caps. Recognize destroying angels by their white stalks and caps. Avoid mushrooms with white gills and/or a volva. Never consume mushrooms you are not 100% sure about.
