If you have a stash of old milk cartons hanging out in the recycling bin, you'll love this seaworthy (or at least bathtub-worthy boat) craft project idea. These fun pirate ships are made completely with objects from around the house (use straws and scrap paper for the sails). The even cooler thing is that the boats float, so you can take an armada of ships to your favorite tub or kiddie pool. Find instructions here: Craftprojects.com
