Making a Vacuum-powered Dragster

Using large syringes, Tom Stanton shows us how the vacuum captured inside can be used to drive gears, a belt, and an axle. The result is a mini dragster that travels an impressive distance compared to the short distance that the syringe’s piston moves.

If you’ve ever handled gold leaf, you know how fragile the thin metal sheets are.
