The Mythbusters made hovercrafts last month. They always warn us not to try what they do at home- but this was too good of an opportunity to turn down. So for Galen's birthday we made a hovercraft- sure beats normal party games!
Grandpa started by cutting the wood to build the platform. And then moved us all the the cob building for the actual construction (see Ian carrying the wood) and made the boys vacuum all the dirt so the hovercraft wouldn't blow it all around.
