Ok, here is another simple one, which I remembered:

There are 10 wallets with 10 coins in each of them. In one wallet each coin is false, e.g. if true coin weights 1g. (sorry, I use metrics system :)), the false coin weights 0.9g. There is also precise scale. Attention, here is the question: how can you determine the wallet with all false coins in one operation (You can weight only once).
