Hovercraft

Gideon and Jake and their Aunt Rebekah constructed a remote control hovercraft out of balsam wood and propellers. Gideon was very interested in how it worked, and we talked about lift and pressure and the mechanics of how the hovercraft is able to "float" on a cushion of air. We talked about how the propeller had to go really fast to move enough air, because air is so light and the hovercraft is much heavier. Gideon loved driving it around after it was built. We also talked about how the remote control worked off of electricity, and he thought the idea of radio waves telling the hovercraft how to move was pretty neat.
