Can art has been a fascination of mine because it's amazing what people can create from a soda can. Coca-Cola is pretty major in my home state, Tennessee, and you can find soda can roofing on bird houses, wind vanes, and all sorts.
Also, I'm a soda fiend and generally don't drink much coffee or tea which means a lot of my caffeine comes from caffeinated sodas. Consequently, there are always aluminum cans at my house which my husband is now collecting to make big bucks or something.
This Instructable shows to make a flower that can be used as yard art, a present decoration, or a seed packet (or small gift box). The materials are inexpensive and common in many households, and there are minimal skills necessary.
