Balloon Powered Boat

Put the batteries away, we’ve found a new energy source that you can use over and over for as long as you have breath in your lungs. The Balloon Powered Boat ($9) just needs a few puffs of air to cruise across your bathtub or a backyard puddle. It’s designed so that you attach the balloon first, and then blow into a small wooden pipe, so you’re not struggling slip a full balloon over the cylinder without losing all your air. This tiny wooden boat is a simple delight that just never gets old.
