i made this instructable because there are many hovercraft instructions out there but none are specific! so i took the liberty of building one and provided this instructable. it goes about 2" above the ground and costs only $50 to build. EASY!!!!!
Step 1: Materials
2. plastic sheeting at least 4ml (thicker is better)
3. 2 1/2" hole saw
4. duct tape
5. electric blower at least 120mph (I used a homelite two speed $30 at home depot
6. a small bolt and nut with washers
the price altogether was $48.50 all at home depot
Step 2: Cut the Wood
Step 3: Drill the Hole
Step 4: DUCT TAPE TIME!
Step 5: Put It Together
now you need to cut some holes around the center of the plastic about as big as a bottle cap. and tape everything together plug in the blower a ta da !!!! your done to get it off the ground you need to wiggle alot and it should hold it took me a couple times and i broke it many times but until you get the hang of it watch out!
