I always knew pennies had potential. Why else would they still be made? Nobody uses pennies to buy things. It’s 2010, dammit! Well, stop throwing your useless pennies in the trash, sucking them up in vacuums, and tossing them into jars, never to be seen again. Pretty soon, we’ll no longer be allowed to bring pennies onto planes. I can only imagine the damage a nickel would do. You can buy one of these Penny Shooters at Cardnetics, or find out how to make your own at Thingverse.
