In the Cohesion Plates Demonstration Kit for physical science and physics, mesmerize others by "fusing" two plastic plates together with only a drop of water. The kit illustrates the power of atmospheric pressure and more.
Mesmerize your students by “fusing” two plastic plates together with only a drop of water! This easy demonstration illustrates the cohesive properties of water, and shows that atmospheric pressure is a powerful, unusual force. Smooth plastic plates will not break. Beveled edges allow for easy gripping. Complete instructions are provided.
