Our growing spheres have always been popular, and now they've gotten downright gigantic! These spheres start off about 12mm, but once placed in a bowl of water they grow to be between the size of a racquet ball and a tennis ball! The hydrated gel-like spheres are irresistible to feel and explore. They are way up there on the slippery meter and if you break or cut one in half, it can be used as a jelly-like magnifying glass. Water absorbing polymers similar to this are used in agriculture to retain moisture in soil. You'll get 50+ multicolored spheres (with a few clear ones thrown in for fun) which will make gallons of expanded spheres. Includes directions and activities. Jumbo Spheres are also available in CLEAR. For ages 6 and up with adult supervision.
