These tornado tubes are a fun way to teach kids about forces of nature. They're really simple to use- screw two 2 liter bottles together with these after filling them partially with water. I always preferred to put some food coloring in just to make it look more interesting. I love that it includes a booklet explaining the scientific principles at work. For added entertainment throw a monopoly house in there! Tornado Tubes - Desk Toy - Amazon Oddities - Science - Tornado'
