Step 1: Balloon Time!.

blow up the balloon,tie it and tape the ends together
that should make a oval shape.

Step 2: Cardboard Time!

Next cut out a suitable shape to fit the middle of the balloon,then tape it
and yes it does look like a hover craft,and thats good
because you can use it that way.

Step 3: Your Done! Kinda...

well,yes you are pretty much done exept it wont move.
Well you can make it move,you can buy one of those cheap
small fans that run on watch batteries you can attach them upside down so it's propellers are have in the water or you can strap a normal balloon to it and go!.

    Just call it boat... sounds better than water car or water glider.

    thanks for comments,and know it s not a car and thankyou
    for pointing that out.I should have titled it water glider
    or some weird name like that.

    ya, its a cool idea, but on such a small scale, and such lack of instruction if find that this instructable could have been greatly improved, if you could recreate this on a larger scale with better materials, you could really have something here, but overall this instructable is quite useless, sorry
