This is a fun little challenge for those who like to solve problems as they construct something out of nothing. The basic raw material used is a beer can, but any soda can will do. Beer comes in 16 ounce cans which allows for some larger pieces to work with. I like to make my models powered so I am always looking for small DC motors and switches. (Battery powered Crest Toothbrushes have excellent motors)
There is really no definite right or wrong in building a beer can model. It actually boils down to your imagination and how great a challenge you want to accept. These slides will show you some areas that really stumped me for a while. For the rest, you are on your own.
