Experiment Details

Items Needed
===========
2 Ping Pong Balls
String (2 piece of string each 2+ feet long)
Tape
Drinking Straw
Stationary Object to hand strings from (i.e. Door Frame, Shower Curtain, Clothes Drying Rack)

Instructions
===========
Step 1 - Gather two ping pong balls, and cut two pieces of string that is 2 feet in length or longer (length will depend on where you are hanging the string from)

Step 2 - Tape one end of one piece of string to the first ping pong ball. Tape one end of the other piece of string to the second ping pong ball.

Step 3 - Hang the other end of the string to a stationary object. The objective is for the ping pong balls to hang freely in the air at the same level and about 4 inches apart.

Helpful Tip: We used a clothes drying rack. You could also tape them to a door frame or hand them to a shower curtain rod.

Step 4 - Make sure the ping pong balls hang in mid air at the same height about 4 inches apart.

Step 5 - Use a drinking straw to blow air directly in between the ping pong balls. What happens to the ping pong balls when you do this?
