Soda Pop Can Cow

From Sherri Osborn, former About.com Guide

Start out by removing the tab on the top of the can. Then squeeze the pop can so the top bends down one direction and the bottoms bends up the opposite direction. Lay the can on a flat surface and step on it to flatten. Have a few extra cans on hand because the crushed can doesn't always look the way you want it to look! Once your can is crushed, watch out for sharp edges. If you are concerned about any sharp edges, cover them with a small piece of masking tape.
