Product Description

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.
