Pet Tornado!

Each tornado that occurs in the U.S. is ranked from F-1 to F-5 (the FUJITA scale) depending on its estimated wind speed and degree of damage. Now nature's most destructive force can be observed and enjoyed. Shake the Pet Tornado clockwise and watch the funnel form. F1-F5 tornado information included right on the toy. Perfect addition to a weather science curriculum. And it's made in USA!

Directions: This is a liquid filled plastic toy, you shake it and bubbles are created, then you hold it upright and shake it briskly in a clockwise motion and watch the tornado form. It's very realistic looking and a great way to observe what a tornado looks like. No box included, directions and all tornado information is printed right on the toy.
