Just Add Water Amazing Science Kit

Liquids can't flow uphill and even disappear, can they? With this amazing kit, you'll mix up your own batch of gravity-defying goo that flows uphill as it "self-siphons" from one cup to another

Use the fizzing color tablets to make the "goo" in all kinds of colors, or add Pearl Swirl to turn it into a pearly, swirly, adventure that will help you see how the goo is moving and grooving.

Also included are the amazing "Clear Spheres" and colorful "Garbled Marbles" that absorb up to 300 times their weight in water to become slimy jelly balls that bounce.

You'll learn to connect these spherical wonders to your Gravity Goo so that it takes them along for the ride as it sneaks uphill.
