Description

The “Coin and Feather” experiment is one of the best ways to dispel the “lighter objects fall more slowly” myth.

When the air inside the 75 cm tube is at atmospheric pressure, the feather (in this case a very visible piece of Styrofoam) falls significantly more slowly than the coin. The syringe vacuum pump (included) will bring the air inside the tube down to about 7% of atmospheric pressure, making the feather and the coin appear to drop at the same rate.
