[Q]: [header] How to warm a horse's bit [title] Dunk in hot water, then wipe dry. [step] Heat water until it's just begun to steam, then bring it over to the stall in a bucket. Place a safety hook over the bucket and drape the bridle over it, making sure not to let the leather touch the water or the ground. <sep> (A) Dunk the bit for 10-15 seconds in hot water, or 1-2 minutes in lukewarm water. Wipe the bit down with a cloth to dry it. (B) Try to keep your head at least six inches from the water. The halter and bridle should be crimped, not tightened, to avoid fraying. (C) [substeps] You don't want the bridle to get hot. If this happens, you need to bring a band-aid or thick covering of newspaper over the cloth. (D) Smooth out any wrinkles so the bridle stays in place. [substeps] When you go to wash the bridle, look in the mirror to see if it fits.

[Q]: [header] How to make a millipede habitat [title] Select the right size container. [step] A glass or plexiglas aquarium is ideal for housing millipedes. You can find one of these in a pet store. <sep> (A) A 3-gallon (3.8 l) aquarium is a good size tank to make. It is best for 6-10 millipedes, a larger tank 6-10 millipedes, a larger tank 13-20 millipedes and a smaller tank 10-15 millipedes. (B) [substeps] That being said, all millipedes grown in captivity should be at least one meter in length. They should have a clean surface, such as a glass or plexiglas tank. (C) The container should also be wide enough so that your millipede can hop into it comfortably without getting injured. [substeps] Choose one that has sides that are equal in diameter to one inch (2.5 cm) thick. (D) Such a tank will allow you to easily observe the millipedes and control the lighting. Plexiglas (hardened transparent plastic) will be lighter in weight, so this may be the best choice if you plan to take your millipedes along with you now and then.
