In less than one day, Slippery Spheres will expand to over 200 times their size as they grow to the size of a marble! They will slip, slide and bounce. The more water you add, the bigger they get. To keep them hydrated, store in a sealed plastic bag or container. Or let them dry out to use over and over again. Slippery Spheres are completely reusable, safe for ages 4 and up, non-toxic, and environmentally friendly. Great for use as a science project or as a stocking stuffer.
