Air leaving this 'cannon' flows like a smoke ring and travels for quite a distance before hitting a target of small 'flags'.
Bernoulli Beach Balls
Blow air between two hanging beach balls. The surprising result explains why aeroplanes fly!
Bernoulli Blower (large)
A beach ball is suspended in the fast airflow from this blower.
Bernoulli Blower (small)
A beach ball is suspended in the fast airflow from this blower. (Built to travel.)
Bubbles float up tubes containing different liquids. Bubble speed depends on the viscosity of the liquids.
Compare the speeds and shapes of bubbles rising in tubes or oil and water.
Hot Air Balloon
A model hot air balloon rises to the ceiling as visitors heat the air inside and sinks as it cools.
Experiment with Newton's second law using a trolley on a track.
Convection currents from a small heater in a water tank are revealed as shadows when light is shone through the tank. Why does this
