The use of e-rubber band is well known. Its use is known in some garments and especially in socks. The properties of elasticity of some substances have made our daily life easier. Rubber bands are a very useful item. Solids do not shrink or shrink by pushing or pulling, but many objects, such as rubber, shrink a little and return to their original position by removing pressure. This quality is called elasticity. The iron is not elastic but the spring made of thin wire is elastic.
Man's bones are also elastic. Elastic materials can withstand more shocks and do not break down quickly. Pulling the thread warp breaks but pulling the rubber lengthens but does not break.
Atoms in position-establishing objects are arranged at a certain distance from the potential pressure. There is little space between the atoms and the weight is less according to its size. Rubber is called the highest position installer but that is not true. Steel spring is more resilient than rubber. Pulling the rubber band more often makes it longer than the original position but the steel spring is pressed or stretched thousands of times but retains its original shape.
