Answers the Question- Do heavier objects fall faster than lighter objects?

Easy to set up and economically priced, our Coin & Feather Demo can be used to perform the classic experiment of a lighter object falling at the same rate as a heavier object when air resistance is removed from the equation. The demo includes a metal disk, a feather and a transparent free fall tube. The tube easily mounts on a ring stand with a clamp (not included) or can be held by a student. The acrylic tube is 100cm long and 3.75cm in diameter and is equipped with an evacuating valve. Any electric vacuum pump that reaches 24-27 in. Hg can be used. We recommend our Electric vacuum pump to work with the Coin & Feather demo. 

Please Note: With the hand-held vacuum pump, you will not achieve a full vacuum (25 in Hg ,85kPa), but the effect of the lowered air pressure will still be noticeable.
