We used to make tin can stilts as well. Lots of fun but they could be quite dangerous.Many a twisted ankle on various kids. I'm not sure that you would call this recycling exactly but when we were little there wasn't enough money to buy toothbrushes and toothpaste (occasionally we used to have a tin of toothpaste) but our mother stood over us while we used our forefinger dipped in salt to clean our teeth. It didn't taste very good but it certainly cleaned our teeth and we still have them. image Hazel
