Description

These are a ball of fun! They start off as tiny (2-3mm) balls, but when you place them in water overnight, they grow into crystal clear gel-like marbles that are 200 times thier original size! They not only look cool, just wait until you feel them. Can it get better? Yes it can...if you drop them back into water, they suddenly seem to completely disappear. The spheres are about 99% water once they have expanded, and they diffract light in the same manner as water. This means they virtually disappear when submerged. You can even color the spheres by expanding them in water with your own food coloring.

MEDIUM - Grow to about 2.5 cm
