Air Pressure

Title:Air Pressure



To see what will happen when a ping pong ball goes on 


Hypothesis/Prediction (What I think will happen and why?)


Tyrones: the ball will start to float then fall off

Ryan: The ball will float on the air waves coming out from the hair dryer.

Helena: I think that the ping pong ball will float on the air that is coming out of the hair dryer as long as long as the hair dryer is switched on, but it’ll fall off  If the hair dryer is switched off.




Ping pong balls and hair dryer 




Place the ping pong ball on top of the dryer and see if it will move around and stay in the air hope fully the hair dryer will keep the ball in the air and you will be able to move around with the ball staying in the air 




Because the hair dryer was old the air kept making the ping ball fall off as the watts were not strong enough to keep the ball in the air long enough. 




In conclusion the ping pong ball will fly up from the hairdryer until it reaches a point that the force of gravity pushing down on the ball is equal to the force of the air pushing up on the ball. We all had fun and we learnt something new about air pressure and hair dryers.
