Forces in Moving Fluids – 2C20.00
Bernoulli’s Tube – 2C20.10
- Blow across the top of the transparent vertical tube with Styrofoam plug.
- Observe how the Styrofoam plug rises demonstrating how the Bernoulli effect causes the pressure in moving air to become less than atmospheric.
Location: Jacobs B12 – Shelf 286
Wind Bags – 2C20.22
- Blow into a long tubular plastic bag known as a “Wind Bag.”
- If the bag is placed right over the mouth, it will barely inflate when blown into.
- If the bag is held a few inches away from the mouth and blown into, it will inflate a much greater amount, as air in the region is pulled into the stream of air entering the bag.

Bernoulli’s Funny Car – 2C20.35
- Demonstrate Bernoulli’s principle by supporting a Styrofoam ball in a stream air.
- Put Styrofoam ball on smokestack.
- Move switch to GO position.
Location: Jacobs B122 – Shelf 281
Singing Boogle Tube – 2C20.36
- Hold at one end and swing the tube to hear the not. Adjust the speed of the tube to obtain higher or lower pitch.
