It’s easy to setup and you can have fun with your kids.
Setup a blower as shown in a movie and turn on the switch.
Please note that hot air may be dangerous to the ping-pong ball because the air generates by a blower.
Put a ping-pong ball on the generated air gently!
Observe the ping-pong ball is dancing.
Did you know that the ping-pong ball can float in the air?
Hope you and your kids enjoy the exam.
