It was on this day, 17 March 1845, that the elastic rubber band, made from vulcanised rubber, was patented by it’s English inventor Stephen Perry. Around the same time, Jaroslav Kurash also independently came up with his version of the rubber band.
While this counts as the ‘invention of the modern rubber band’, it is by no means the first occurrence in history of these super-useful little binding tools. Many years before the Mayans had already used the sap from rubber trees to create elastic strands to bind things together.
From their modern-day invention in 1845 it took almost 80 years before William Spencer first started mass producing rubber bands in Ohio, USA. And the rest, as they say, is history – it is nigh impossible to imagine a world without rubber bands.
Throughout history two types of rubber have been used to manufacture rubber bands – natural rubber or latex from rubber trees, and synthetic rubber, a by-product of crude oil refinement. Modern day rubber bands are basically created by extruding rubber into long tubes of varying colour, thickness and diameter. These elastic tubes are sliced into thin circles, creating rubber bands as we know them.
Very simply stated, rubber consists of chains of molecules bonded in such a way that the molecules can move, thus allowing the rubber to be stretched. The bonds between the molecules pull them back together again, causing rubber’s elasticity. Of course it is possible to stretch a rubber band too far, severing the bonds between the molecules, and causing the rubber band to snap. Over time, light and heat also weakens the chains of molecules, resulting in the bands to get brittle and more readily breakable.
Can you believe that the biggest rubber band ball (a ball created by wrapping rubber bands around each other ) was created by Joel Waul in 2008 in Florida, USA? It weighed a whopping 9400 pounds, exceeded 8 feet in height, and consisted of more than 700 000 rubber bands!?
