Description
Not the Drinking Kind...
Decidedly clever little gizmo reminiscent of our ever popular tornado tube. It consists of a plastic sleeve into which one screws two empty 2-liter soda bottles. Inserted into the connecting tube are clear plastic "straws", one extending toward the bottom of each bottle. Fill one bottle 3/4" full of water, colored if you like, invert the duo, and watch water spew from the top end of the top "straw". It is all because of the vacuum created as the water drains from one bottle to the other and is a great physics demo item. It looks as though the water defies gravity. Instructions/description are on the package.
