Falling Feathers

Falling Feathers | Science Fair Projects | STEM Projects
Have you ever wondered if a feather and a coin fall at the same speed? Galileo thought so, and you can prove it yourself with this experiment!


The hypothesis is that a feather and a coin will fall at the same speed in a vacuum.

Method & Materials

You will need to build a vacuum tube, put a feather and a coin inside, and then pump the air out of the tube.
You will need a clear plastic tube, rubber stoppers, copper tubing, vacuum tubing, a coin, a feather, and a vacuum pump.


The experiment showed that when the air was pumped out of the tube, the feather and the coin fell at the same speed. This is because the feather's lightness is balanced out by the air resistance it experiences, making it fall at the same rate as the coin.

Why do this project?

This science project is interesting because it allows you to prove a scientific theory in a fun and easy way.

Also Consider

Experiment variations to consider include using different objects of different weights, or using a longer tube to see the effect more clearly.
