Connect two plastic bottles and create a fascinating tornado!
Fill one bottle with water and screw on the tornado tube. Then screw on another bottle and flip it over. The water will flow very slowly - or maybe even not at all. If you swirl the water in the upper bottle, a tornado forms and the water will begin to flow very fast. Add to the effect by using coloured water. The tornado will inspire discussions on subjects from energy transformation to pressure in liquids.
Material: Plastic.
Dimensions: Height 4.8 cm.
Accessories: Plastic bottles not included.
