Such a simple piece of equipment to make a tornado! Take 2 plastic drink bottles of the same size and fill one with water. Join the bottles with the vortex valve and invert. Watch as the water spins to get through the small valve into the empty bottle. Add some food dye for added interest. A very effective experiment best done outside!
