While continuing to unpack at the house, I have discovered something from my misspent youth: my milk jug full of aluminium can pull tabs. You know how you can sell those things for a lot of money, right? (I think McDonalds will give you $75 for them.) Or you can save them up, for the children. Here's a link telling you how to redeem them. ...Or maybe not.
Sigh. Well, at least at the end of the day, I have a milkjug of Aluminum pull-tabs.
