Amphibious Altoids Car
This is a car that I made from my altoids boat. It is pretty much the exact same thing. All you need to do is put some lego wheels on the bottom of the altoids tin. The propeller is used to push the vehicle forward on land, and it acts as a paddle in the water. It works well, although it sprays up a bit of water. Have fun! (look at my other instructable for the original altoids tin boat.) I made this instructable to increase the number of entries on the weekly challenge (wheels.)
