Sliced foam is amazing as a light weight and miraculously durable material. To get back to your point of using nonstandard materials (yes?), I just made a tumblewing out of a plastic shopping sack. It is hard to work with but holds its shape because of the folds and because it doesn't weigh anything. Blow too hard and it will crumple. I'll try and put together some data of the weight per unit area of the plastic films I scrounge up while shopping or in my hotel room. I'm always thinking back to the butterflies which skillfully evade danger rather than rely on durability for survival. And you can never be durable enough, armadillos don't even fly and they are becoming scarce because their strategy of rolling up into a ball is no match for a speeding car. So what you'd think wouldn't work because it appears to have no strength might just hold together and fly!
