My son has this totally awesome “exhaust” pipe on his bike that I covet. It’s really a resonator for the classic baseball-card-in-the-spokes trick. It makes a terrific racket, and gets people to move out of the way without necessitating a honk on your horn. I decided to build my own, using a recycled beverage bottle. Armed with a Dremel Rotary Tool, a bottle of energy drink, and a depleted gift card, I set out to make my own soda bottle bike exhaust.
Materials: Dremel Rotary Tool cut-off wheel, 180- and 280-grit abrasive buffs, aluminum oxide grinding stone, and 1/8″ drill bit Aluminum 16oz. beverage bottle Hose clamps (2) Plastic gift card (depleted) #8 screw (1) with nuts (2) and washer (1) Pop rivet gun with 1/8″ short aluminum rivets Permanent marker Masking tape Dust mask Safety goggles
