this Instructable will show you how to build your own hovercraft for less than $50. it will also show you exactly how the hover craft works.
Step 1: Materals
for this project you will need:
1 whole sheet of plywood (can be bought at lowes)
2-5 in piece of 3 1/2 in pvc pipe
1 3 1/2 in elbow joint
3 1/2 drill bit
visqueen (the stuff painters lay out before painting)
entertainment (if you want)
electric or gas leaf blower
Step 2: Build the Board
for the board you will cut ur plywood into 2 equle peices. once you have done that you need to drill the hole for the pvc pipe, i subjest clamping them toghther before this. and then round the edeges of the board.
Step 3: Plastic Power
lay out one of the 2 pieces of the board and role out enough visqueen to tuck in between the two boards but no more than nesasary. now tuck the visqueen between the two boards and secure with screws ( dont worry if you put a hole in the visqueen and tuck the corners under too)
Step 4: Holes
befor we begin to make the holes that will allow the air to escape we need to screw a plastic lid (from a butter tub or something) to the center, this will create the air pocket. next cut holes as close to the lid as posible you will need to test it to find out how big the holes need to be
Step 5: Pvc?
now cut your pvc pipe to a length that will allow you to stick the blower in it and another to put on the other end so it just goes throught both layers
Step 6: Paint Time Better Get Some Visqueen
noew u can put your little designs ans stuffon the board if you want but since i suck at art i left it blank
Step 7: Put It Together
now just conect up ur blower and ride away into the sunset
please note it works best on smooth surface
