Article no.: 21.0002D
Start by filling a Bottle with about 2/3 of water. Then screw on the tornado tube and another bottle.
If you turn it upside down, the water will flow very slowly or not at all.
How could you get the water down the empty bottle faster?
If you spin the water in the upper bottle, it will form a tornado of air inside. Air enters the upper bottle and presses the water into the lower bottle (like in a bathtub). This is very fast
People of all ages are captivated by this example of nature's most violent and unpredictable phenomenon.
You can also create your own effects by adding caramel color to the water. Give your Tornado an extra spark by adding glitter to the water.
