We just love super absorbent polymers. Now you can have the wonder that is polymer suspended and swirling randomly in a water filled lamp. A built-in propeller system in the bottom of the lamp propels the spheres, creating a mesmerizing water show. The water lamp comes complete with a packet of translucent multicolor polymer spheres. Once they absorb water, they grow to 20 times their original size! Simply soak them for about 24 hours before adding them to the lamp. Just add water to the lamp, then add your polymers, and voila!Pure entertainment that totally thrashes your old lava lamp, man!Colorful jelly balls rise, fall and float-a mesmerizing sight.Uses 3 AA batteries or an AC adapter (not included).The scene is both mesmerising and calming.
