Rubber bands are made by extruding the rubber into a long tube to provide its general shape, putting the tubes on mandrels, curing the rubber with heat, and then slicing it across the width of the tube into little bands.
Only while the rubber bands are on it. Keeps the blood in and over inflates it. Do this too long or too tight and you can injure yourself.
You really can't know that without knowing the type of rubber bands involved, how much each of them weighs, and how long each of them is.
it dosen't stretch for too long and also if it snaps it is very painful
first get a clean solid white tee. next twist it. it should be long and skinny. wrap rubber bands along the shirt. if you want thicker strips, put less rubber bands. if you want thinner strips, put more. squirt the dye on the shirt where the rubber bands are not there. let it dry. wash it. and wear it! :)

usually the rubber bands are to correct overbites and therefore if the intensity of the bite is medium, it is kept in for just six to twelve months. Also if you wear two on each hook, it speeds up the pace I've been wearing my rubber bands for a month now...and they dont bother me that much. You'll probably have 2 wear them 1, 2, or 3 months....depends on your situation
Yes because you could stretch the rubber band long and it will go far but if you stretch short it will not go as far. the materials you need is rubber bands a tape measure or meter stick paper pencil
The Rainbow Loom is a long plastic peg board to put small silicon rubber bands on in various patterns. These rubber bands are then looped together, one to the next, using a tool (hook) or crochet hook. After all the loops are connected, you can take all the bands off the loom and it is a friendship bracelet. The Rainbow Loom can also be used to make necklaces, charms, headbands, cell phone pouches and action figures.
Rubber and a number of its uses had already been discovered in the Americas by the native populations long before their countries were colonized. So datewise the only thing we know for sure is that it was discovered (long) before 1492.
Urethane rubber is actually not rubber. It is known as urethane elastomer and is cheaper than Silicone rubber. However, it does not last a long and requires the application of a release agent before every casting. It is cheaper than silicone rubber and has a higher tear strength.
