# Parachute Toy

Have you ever ridden a bicycle down a hill and felt the wind on your face? Air is all around you. To move through it, you have to push it out of the way. That means it's pushing back on you, too. That push is called air resistance. Imagine a parachutist jumping out of an airplane and falling to the ground. The opened parachute would use air resistance to slow down its descent. In this experiment, we create a parachute toy using a Ziploc® brand sandwich bag to learn about air resistance and see it in action.

• ## Step 2

Use soft felt-tipped permanent markers to decorate the Ziploc® brand sandwich bag. This will be your parachute.

• ## Step 3

Turn the top edge of the bag inside out to keep the bag open.

• ## Step 4

Cut two pieces of string, each 14-inches long.

• ## Step 5

Cut a piece of straw 2-inches long.

• ## Step 6

Pull one of the strings through the straw.

• ## Step 7

Reach into the bag and pull both bottom corners in, so they’re inside the bag.

• ## Step 8

Tie each end of the string to each inside corner of the bag.

• ## Step 9

Pull the second string through the same straw.

• ## Step 10

Tie your small toy to the second string, so that your toy becomes attached to your parachute. It’s now the passenger!

• ## Step 11

Find a high point to drop your toy. You can go to the top of a set of stairs or stand on a chair. Drop the parachute and watch its descent! To see air resistance in action, simultaneously drop the toy with the parachute and an identical toy without a parachute. How much longer does the toy with the parachute take to fall? Can you think of a way to extend the duration of the fall even longer?
