Warm rubber shoots faster than cold rubber. Therefore, The Slingshot Channel tests a new, experimental slingshot that can heat the rubber bands to about 60 centigrade.
The heating system employs copper pipes, filled with boiling water, and valves for easy refills.
The speed advantage is measured, the difference is about 10% more speed!

Dramatic High Speed scenes of slingshot action. Watch heavy steel balls shattering bottles and smashing oranges at 300, 600 and 1200 frames per second. This is must-have-seen stuff for every slingshot enthusiast. The casio EX-F1 Pro camera was used for the high speed shots.

his video is one more experiment in order to find out the truth about how rubber works. We know now that bands warm up when drawn out and cool down when released. We also know that when the drawn out bands cool down to room temperature, they loose a bit of their power. Heating up those bands brings all of the lost power back.
This pretty much supports the “Entropy” model. When you draw out a rubber band, you bring order into chaos, and this generates heat. When you let the bands swing back to chaos, this heat is lost (converted into kinetic energy).
But there was one thing that was missing: What happens if the bands are getting very cold? This was tested today in this video. Bands were drawn out and left out in the cold, until they reached about minus 6 centigrade. They loose all of their stretchiness! Funny wrinkles appear instead.
Drawing the bands out and letting them snap brings the stretchiness back.
Also, a new slingshot is presented, this time with the rubber bands wrapped around a Zippo handwarmer…
A “The Slingshot Channel” production.
