Introduction: Water Bottle Boat
This boat is made out of a motor, fan, water bottle, film canister, wire, tin foil, and a C battery. The water bottle glides above the surface while the motor is submerged.
Step 1: Materials
The items you need are:
plastic fan blade (not shown)
0.5L water bottle
Sorry-You won't need the rocks : )
Step 2: Battery Pack
Now you need to punch two holes. One hole goes on the lid of the film canister and the other on the side of the canister itself. You can use an ice pick to poke the holes. Follow the picture examples.
Step 3: Battery Pack Wires
You need to wrap the end of the wires in the tin foil then attach them to the film canister. Keep folding the tin foil around the wire until it will fit in the film canister. Allow enough space for the battery also to go inside the canister.
Step 4: Completeing the Boat
Use hot glue to attach the film canister assembly to the water bottle and attach the motor to the opposite end allowing room for the fan to hang off the end of the bottle.
Step 5: How to Run This Boat
Your boat will turn on or off by placing the cap on or removing from the canister. To keep the motor from rusting you should probably put some WD-40 on it after running it under water and allow it to dry well. Have fun! : )
