Just add water and watch as this liquid seems to pour itself up and out of the cup
Everyone knows water won’t flow uphill without a push. A small amount of Gravi-Goo powder mixed with water forms a thick, slippery, gooey, mucous-like gel. The gel crawls up the inside of one container and pours into another.
How does it work?
Specially formulated by Spangler Science, Gravi-Goo is a unique type of polymer. When added to water, it acts both like a sponge to grab water molecules and link them to the polymer molecules in long chains at the same time. Gravi-Goo is a combination of polyacrylamide and acrylic copolymers.
What does it teach?
Gravi-Goo is a great introduction to molecular weights and structures. Children will marvel at this fascinating goo and learn a lesson about polymers at the same time! Watch out though, even adults have been known to become addicted to the uphill flow of Gravi-Goo!
