Science Projects For Kids: Bernoulli’s Theorem : Golf Ball Demonstration for Bernoulli’s  Experiment


Hi! I’m Scott Thompson from expertvillage.com,
and today I am going to demonstrate Bernoulli’s theorem using a soda bottle and a ping pong
ball. Once the students have had a chance to play with this activity, you can kind of
shift gears a little bit to a similar demonstration, but a little bit different, that uses, instead
of someone blowing, it uses the airflow out of a shop vacuum hose. You will probably have
to switch the hose around in configuration, so the shop vac—you are using the exhaust
air from it instead of the air getting sucked into it. Get your shop vac ready, and this
is where the little heavier ball comes in handy. You might have to play around with
this ahead of time to make sure that you got the right weight ball for the amount of airflow
coming out of there. Put the ball on and turn on the shop vac.

  1. This works waaay better if you use a balloon with just a little dab of water in it. Floats far higher, and you can lean it over almost 45 degrees and it'll stay in the air stream…which is definitely Bernoulli's principle in action.

  2. When I do this demonstration, it works way better with a balloon with a little bit of water in it. You can levitate it several feet and even lean it over nearly at 45 degrees.
