In 1828, William H. Spencer invented them. Thomas Perry made the first rubber band company. Now, they are used for lots of activities. P.S. Please Google for more information.....

Yes. Rubber bands are thermoset polymers. Unlike thermoplastics, they do not melt or turn rubbery/soft when heated above their glass transition temperature. Instead, when they are heated, they decompose, losing mass, breaking up their polymer chains and become more weakened in strength. There are also other ways that they can decompose, which is due to UV light from the Sun or other sources attacking the polymer chains of the rubber bands. This also causes it to weaken.
no it does not change the elasticty if any thing it makes the rubber band smaller.What effect does heat have on the elasticity of rubber?That is not an easy question to answer but the heat stretches the rubber band because the molecules have to arrange or move themselves around. When a rubber band isn't being stretched the molecules are in a srtaight line.

the elastic band was invented to hold envelopes and pieces of paper together.

Rubber bands are very elastic. They demonstrate perfectly the property of elasticity. Some people even call rubber bands "elastics."
Yes, rubber bands are made out of rubber.(:
its not clinical and i would ask your doc before doing it but for me double rubber bands worked well.
Rubber bands stretch because of the latex in them and because they are elasticey.
There is no way you can get free rubber bands but at amazon they are selling rubber bands for 10.99$
There are 153 rubber bands in a box (17 newspapers x 9 days = 153 rubber bands).
