On Saturday February 9, 2013 my daughter and her friend helped me build a hovercraft. In just two hours we were floating across the floor!
We started with one 4'x4' piece of plywood (4 ply) that is 1/2 inch thick.
Lift is provided by an electric TORO leaf blower but I plan to upgrade to a cordless (battery powered) leaf blower.I prefer electric over gas power because I plan to only use this indoors.
For the hovercraft to move forward it must be pushed (or pulled).
The hovercraft worked great on the cement floor of the warehouse. It did not work well outside on asphalt (pavement).
This hovercraft was inspired by a project in the MAKE Magazine blog HERE.
