2B60.30 - Siphons, Self Starting Siphons, & Tantalus Cups

Code Number:
Demo Title:
Siphons, Self Starting Siphons, & Tantalus Cups
Pressure vs. Water Height
Area of Study:
Heat & Fluids
Skimit Magic Siphon, Homemade Glass Siphon, and Siphon with Squeeze Bulb.

Video Credit: Jonathan M. Sullivan-Wood.

Fill the Plexiglas cube nearly to the top with water. The homemade glass and the Skimit siphons are self starting. Insert and hang these on the edge of the Plexiglas cube. The siphon flow will start automatically.

The bulb siphon uses vacuum to draw the liquid up into the tube. The bulb may have to be squeezed several times to get the liquid to the proper height.

The Tantalus or Pythagorean cups are nothing more than self starting siphons. Very cool but watch out, you will get wet if you aren't careful!!
