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
