Great fun! Cyclone Tube is a special plastic tube that recreates the fantastic effect of a vortex. The water traveling through the tube builds kinetic energy as air transfers from the lower bottle through the hollowswirling funnel above. There are several occurrences in nature that demonstrate the powerful energy created by a vortex. Cyclones, tornadoes, whirlpools, hurricanes, and even your bathtub creates this unique form of kinetic energy. The small initial swirling of the top bottle causes a chain reaction of increasing rotational velocity, which propels the water molecules closer and closer. The resulting outward force prevents the water from permeating the center of the vortex, thus keeping a constant spinning opening of water. Packated on a blister card with instructions of the back. You will need two empty 2-liter soda bottles (not included) and water. Warning: choking hazard Small parts. Not for children under 3 years of age. Recommended for ages 6 and older.
