Air-mazing Fun at Science Club

This round of science club sessions was all about Bernoulli’s Principle; this is where air pressure decreases with increasing air flow speed. The children had fun demonstrating this with a hair dryer and ping pong balls, as well as with a leaf-blower that was used to rapidly unravel (clean!) toilet rolls.

They also managed to inflate long thin plastic bags with one single  breath, by blowing slowly into the bag as a steady stream of air.
