Materials:
1. 4x4 piece of plywood
2. heavy duty shower curtain
3. duct tape
4. staple gun
5. leaf blower
6. sand paper (optional)
7. saw
8. box cutter
9. 5 small screws
10. screw driver
11. stiff piece of cardboard or whiteboard


Things That Went Well and Things That Didn't

Almost everything went well. The thing that did not work in our favor was when we stapled the curtain down in random places. It began to rip up the staples and put holes into the top. We fixed that by putting the staples over the tape. Everything else worked very well! We were the best and had the most sucessful hover craft in our class.

Physics Concepts Used:

2. Friction
3. Newton's Second and Third Law

Step 5 - Staple the top of the shower curtain to the plywood. Only staple over the area of the tape and the corners where the shower curtain folds over.

Step 6 - flip the board over so the bottom is facing up. Take a piece of whiteboard or stiff piece of cardboard and cut it into a circle with about a 5 inch diameter, this is the "wooden seal". Place the circle exactly in the middle of the board and screw it in.(see diagram for screw placement)
