What does the hair dryer blow out?
Air
What happens to the ping pong ball in the air stream?
It floats
What does air pressure mean?
Air pushing on things
What is the Bernoulli Effect?
When fast air pushes less
Why doesn’t the ball fall?
Because the air pushes it up
Which part of the air has low pressure?
Fast-moving air
What does the word float mean?
To stay in the air or water
What tool do we use in this experiment?
A hair dryer
Where do we place the ping pong ball?
In the air stream
What happens if you move the hair dryer a little?
The ball still floats
The ball floats because water pushes it up.
False
Air pressure means air is pushing on things.
True
The Bernoulli Effect says fast air has high pressure.
False
A ping pong ball is too heavy to float in the air.
False
We use a hair dryer to make the ball float.
True
Fast air goes around the ball and keeps it up.
True
