Gravi-Goo Gravity and Motion Experiment
Learn About Newton’s Laws of Motion
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 that crawls along the inside of one container and pours itself 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 like a sponge, grabbing water molecules, and then links them to the polymer molecules in long chains simultaneously. Gravi-Goo is a combination of polyacrylamide and acrylic copolymers.
What can students learn from Gravi-Goo?
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.
Although Extremely Elastic, the GraviGoo Remains Fluid Like a Pancake Syrup!

How Many Times Can You Perform the Gravi-Goo Experiment?
Goo With a Mind of Its Own
Aspiring young scientists will enjoy experiencing the weirdness of polymers when they work with Gravi-Goo from Steve Spangler Science. Gravi-Goo is a polymer powder that, when mixed with water, forms a thick, gooey gel. This gel is actually a fusion of polyacrylamide polymers with acrylic co-polymers that form a substance that is so sponge-like and strongly linked that it follows itself around, behaving differently than normal liquids. When the kids pour the mixture after it has thickened, all of it flows together as though it were alive. You may have to reassure students that the goo won’t take over the entire classroom.
