Inspired by MightyBargainHunter's article Ten unconventional uses for the penny, I decided to add 5 more unconventional uses for the penny.
1. Stacking pennies to create bridges, domes and pyramids. Examples from Fincher.Org
2. Squish the pennies and open your own museum. Squished Penny Musuem, Washington D.C.
3. Create a Lucky Penny Pin, or a Penny Garden Stepping Stone
4. Instead of painting your car, Cover it with pennies
5. Buy a bar and cover it entirely in pennies
