Why does a rubber band becomes loose after repeated use?
When the elastomers and plasticizers begin to oxidize over time, those materials stop performing their functions and providing the elasticity that we know and love in our rubber products. The snap-back benefit of a rubber band begins to disappear as those natural chemicals begin to break down.
What affects the elasticity of a rubber band?
We believe that, as the temperature of the water increases, the rubber band will become more elastic, and therefore it will stretch further. The temperature of the water is the independent variable, and the length of the band is the dependent variable.

Why does rubber become brittle?
To make natural rubber, a milky white sap, called latex, is tapped from a rubber tree. Over time, rubber loses its ability to stretch, becoming hard and brittle. This process of perishing occurs because exposure of the rubber to light and air induces chemical changes in the polyisoprene over time.
What happen when you stretch the rubber band and release it?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.
At what temperature does a rubber band melt?
The temperature inside a vehicle on even the hottest of days reaches about 190 – 215 degrees. This would be below the melting point of the rubber band.
Can I double up on my elastics?
DON’T – Double up on elastics as this will cause too much pressure on the tooth or teeth and can actually harm the root of the tooth.
