Gravity Goop Blister Card
Mix up your own batch of gravity-defying goop! Liquids can't flow uphill, can they? With this amazing kit, you'll mix up your own batch of gravity-defying goop that flows uphill as it self-siphons from one cup to another. Just add water (and some mad-scientist back-and-forth pouring) to create this awesome ooze. Use the fizzing color tablets to make the goop in all kinds of colors. This little package makes up a ton of fun--the included powder makes a quart and a half of liquid goop. Also included are the amazing Clear Spheres 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 Gravi-Goop so that it takes them along for the ride as it sneaks uphill. You won't believe this incredible stuff!
