Product Info

We've noticed that people always seem drawn to this interesting demonstration that kind of messing with your mind. Ultimately it's a great disply piece that illustrates the principle of center of gravity! A small hole in an oak board allows you to balance a 2-liter soda bottle at an angle that appears to defy gravity. Use as a teaching tool or a centerpiece at your next party! No, the soda bottle is not included.

  1. How does it do that?

    My 5-6th grade science students love to try to figure out how to make this 2 liter soda balance on a board. Most can't figure it out. (It's even more fun to mess with them first with a board the same size with 2 straight cut ends. Then I pick up the cut board with the angle and instantly it WORKS! Amazing. I agree a great centerpiece on my demonstration table.
