In this chemistry science experiment you will learn how a superabsorbent polymer can change its size and grow more than 200 times its regular size! These hydrophilic spheres love water, and are practically all made of water. By submerging them in water you will see them grow and grow, taking up many different shapes along the way. By using rulers, these little scientists will be measuring the size of their ghost eggs before and after the dunk into colored and non-colored water and be able to tell the change in volume of the magical spheres. The spheres disappear in the water because they absorb the water that surrounds them, giving them the nickname of Ghost Eggs!
