Want a couple hours of fun? Get a soldering iron, and a pack of plastic Cowboys and Indians. In my case I borrowed my father-in-laws soldering iron. ( I think I still have it too!) I imagine you can do it with army men as well. Some were made by me, some were made by my wife's brothers-in-law.
So a couple bucks spent and loads of fun and I even got a free soldering iron out of it. Thanks Rick!
