The bike rim should be in good shape. Don't use a bent up old rim.- Small bolt cutters
Pliers will not cut through the aluminum spokes. You will need a sharp and sturdy pair of small bolt cutters.- Heat lamp bulb
You may use a regular heat lamp from any hardware store or you can purchase just the bulb and use a standard desk lamp as the source to put the bulb.- 3inch Rubberbands.
Rubber bands react the same to heat no matter what size, shape, or width. However, for the best result, I recommend 3 inch rubber bands that are a little thicker and stronger to hold the wheel and axle together.
After you have these materials gathered, you are now ready to begin building your rubber band heat engine.
