You only need four things:
a CD
a push-up water bottle top
a balloon
superglue
Step 1
Superglue the water bottle top to the CD right over its center opening to make a valve. If you don't have a push-up water bottle top you can always use one from an old bottle of dishwashing detergent.
Step 2
After the glue is dry and with the valve in the closed position, blow up the balloon and fix it over the valve in the middle of the CD.
Step 3
Place the hovercraft on a hard and flat floor (not carpet), let go of the balloon and pull the bottle valve to the open position. Watch it hover over the floor as the air escapes from the balloon through the valve.

I love it! It tickles my fancy!!!
Yes, I will make one!!! at least one
My son made one of these at a camp he went to at the Museum of Science Boston called "Toying with Science." Turns out we could have saved money by skipping camp and just sending him to your house! (Except for that darn airfare!)
Too fun! I made a similar version with my Cub Scouts.
That's very creative I will try to make it too
Oh how fun! Thanks so much for the great tutorial, I'll be linking.

That looks like fun! I think that would be a great project for next week in my at home daycare.
