2C20.36 - Coanda Effect - Ball in a Water Stream

See paragraph one in the procedure section
Code Number:
Demo Title:
Coanda Effect - Ball in a Water Stream
Bernoulli's Principle
Area of Study:
Heat & Fluids
Small Single Brass Tube and Ping Pong Ball, Large water tank with drain hole.

The ping pong ball in the water stream is a very impressive demonstration.  HOWEVER: This can be very messy if extraordinary measures are not employed to confine the water.  In our case this would mean the use of the very large water tank.
