this was invented in Wales in 2009 by a group of people called cool. in this group is arron davies, Nathan, Ryan, luke, and James and nidian, it affects the economy by making elastic bands.
you guys are all wrong
Some commodities are rice, rubber, tin and teak (a type of lumber) It is a heavily export-dependent economy.
Yes, temperature effects elasticity. At a constant temperature, and for elongations not too large, a rubber band obeys Hooke's Law. Means the temperature must be constant.an elastic will show more elasticity in cold & lesser in summer relatively. Heating the rubber molecules make them move around more. They become less aligned as a result and the rubber band SHRINKS. so finally it can be told that temperature matters in term of elasticity.

If it is a solid rubber ball it is not inflated. A hollow ball can be inflated. The more pressure inside, the "harder" the ball will be and the higher it will bounce. To much pressure and you risk rupturing the "rubber" bladder.
Vulcanized rubber is process that changes the properties of natural rubber so that it is more usable for products. Natural rubber hardens rock-solid in freezing temperature and melts into goo in summer heat. For an interesting reprint of a Readers Digest article on the invention of rubber - see the attach link.
Vulcanized rubber has disulfide crosslinks and is hard and strong.Natural rubber has no crosslinks and is soft and weak.
Vulcanized Rubber can cost anywhere from one dollar to twenty dollars by the sheet. There are also vulcanized rubber molds you can purchase that range around twenty five dollars.
