Toysmith Bubble Motion Tumbler

This Bubble Motion Tumbler is a liquid motion timer that contains water and oil. Any great chef will tell you that water and oil do not mix, so as you watch the marble-shaped colors in the tumbler, you’ll also notice them zigzag away from each other as they travel downward. It’s also a great visual aid to help see how water and oil separate from one another.

When the small marbles stop moving moving, all you have to do is turn the small tumbler over and watch the colors travel again.

For children who are sensitive to visual perception, this is a great tool to help them focus their attention on something that’s colorful and can help improve their skills in visual perception.
