Everyone knows that water can't flow uphill. Not so fast... when this goo is poured back and forth between two beakers, Gravi-Goo mysteriously siphons from the higher held beaker to the lower one. Maybe water can flow uphill. You have to play with the stuff to believe it. Recommended for children ages 10 and up.

What's included?

• 150 gram jar of Gravi-Goo
• Blue measuring scoop

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!
