Density Experiments & Classroom Tools

Flip Colors in Motion over, and the colors will start to switch places, without mixing! When the Poly Density Kit is shaken, blue and white beads mix as expected. However, when allowed to settle, a surprising change occurs. When the Sandscape is inverted, three different colored sands flow through a clear liquid, starting and stopping as they encounter a hole or a barrier. Rotate the Geological Flow Demo and see new sand patterns forming for the next 30 minutes.
