at Barboursville Middle after school
February 26, 2004
Build a car.
Wear safety goggles. Place a quarter of an Alka-Seltzer in water in a film canister.
(or baking soda in vinegar)
and close the lid.
Place the film container against the wall and the car in front of it.
Wait. Some times it is more than than a minute.
The lid pops off and sends the car rolling.
Record distance was 16 feet. Record time until container popped
was 16 minutes.
