Step 1: The stuff ya'll are gonna need.

DSCN3301.JPG
Ok here's the list (it's all cheap stuff pretty much just laying around the house just screaming, "pick me up and make me into a foam hovercraft) :

1. a 16oz Ajax soap bottle (might clean it out or you'll be blowin' bubbles the whole time)
2. a 8'' by 6'' by 1''ish piece of foam (we used minicell foam but you might something better)
3. a hot glue gun
4. a Sharpie
5. a razor blade (we ended up using something a little more heavy duty, lol)
6. and a balloon (doesn't necessarily have to be green)
7. and something to cut the foam like: bandsaw, hack saw, scroll saw, saber saw, chainsaw!

and thats all your gonna need!

how doesit works?
does the air from the ballon go through the hole that goes through the center and push it up?

I love these hovercraft toys, endless fun! Also, the stopper-top is a nice touch.

a hole drilled through the foam slightly above the bottome could allow enough air oout to make it self propelled
