ID Code: F5-07
Purpose: Illustrate properties of fluid flow in a counterintuitive way.
Description: Place the cardboard piece at the end of the spool with the pin sticking up through the hole of the spool. Blowing into the other end of the spool keeps the cardboard in place. The pin keeps the cardboard from sliding away. It will not blow off! Cessation of blowing allows the cardboard to fall off.
Availability: Available
