I've tried bands cut from inner tubes ranging in size from 1.75-2.35 & 1.95-2.125 mountain bike tires up to 4.25/4.50 motorcycle tires. I cut them to different sizes. I wrap them around different size and shape tins in different directions & different ways. Then, I dunk them under water in my sink for a while, take them out, open them up & dump out the water, every time.<br><br>It sure sounds like a nice idea, and the idea of using them as rubber bands, tinder or simply interesting raw material for improvisation's sake is one I still like. But I haven't yet made them successfully work for waterproofing a tin. If anyone has actually tested this idea and found it to work, would you mind posting a detailed description or pictures, if you have the means? Thanks.
