Have fun
while learning!
Turn two plastic soda bottles into an exciting hydraulic "toy" with the
Vortex Tube. Fill one container with water, join both with the tube, and
create a swirling tornado in a bottle. Introduce your students to the vortex
effect while running tornado "races," testing liquids of different
viscosities, and other demonstrations. Save money when you buy 10 or more!
