With two styrofoam balls.2. See how long you can let the ball float.3. Challenge family and friends.4. The floating ball game is a good example of the Bernoulli principle.5. Since the air is forced to surround the ball, it must move faster to "catch" the other side.6. The result is that the air pressure around the ball is lowered, thereby holding the ball in place.7. The force is strong enough to withstand other forces acting on the ball.8. If the airflow is strong enough, the force can also overcome gravity.9. This can be demonstrated by rotating the socket 15-20 degrees - even if the ball is not directly above the ball, the ball will remain suspended in the airflow.Package1 x ball blower2 x ball
