Toysmith Bubble Motion Tumbler

Bubble Motion Tumbler is a great visualization aid to show how water and oil don't mix. It's full of zigzagging. Liquid motion fun! Turn it over and watch the 2 colored liquid drops make their way down the zig zag steps all the way to the bottom. This is not a toy. Assorted styles and colors. Orders will be filled based on availability. Includes one tumbler.
