Narrator
1: We'd now like to introduce our resident
science expert Professor I.M Hip for some cold hard
facts that may help you with your explanation.
Professor
I.M Hip: Daniel Bernoulli (1700:1782) is
best known for his work with air pressure. He discovered
that slow moving air goes towards fast moving air. The
air coming out of the hair dryer is moving really fast.
The air around us in this room is moving rather slowly.
So the slow moving air actually pushes towards the fast
moving are.
Narrator
1: So professor, are you saying that the
air around us is pushing towards the fast air from the
hairdryer.
Professor
I.M Hip: Precisely.
Narrator

So people, now why do you think the balloon stays in
the air?
