Kayak materials to use as teaching aides? Answered
I teach at a Boy Scout camp in Wisconsin, and one of my main duties is our kayaks. One requirement involves teaching different materials for kayaks (canoeing has the same requirement) and I was wondering if anyone had an idea on where I could get different material samples/scrap/castoffs to use as a teaching aide. Off the top of my head, the materials are polyethylene, Kevlar, Royalex, carbon fiber, and fiberglass. Any suggestions?
