As announced, I have made a slingshot that heats its bands. I want to be able to break records even when it is NOT humid and hot outside! So there was no alternative.
I used water filled copper tubes, as water and copper have the highest available heat capacity.
The bands are put over the copper pipes that are filled with hot water, then the insulation is closed over the bands. They heat up in no time, about ten seconds from room temp to over 50 centigrade. I filled the tubes with hot, but not boiling water as I am not sure how much heat they tolerate.
The slingshot is ugly as heck, but not a bad shooter, it is a "W" after all. And the copper pipes work like a stabilizer.
Here is the video:
