What are Spider Balls and why are they called Spider Balls? Drop one in water and find out: as a multitude of multicolored balls will burst forth from the green sac and grow up to 100 times its size within hours! You can roll throw, bounce and try to squish the balls once they are hydrated. T
The balls will "hatch" quickly and finish in about a half hour as the sac melts. They will be fully hydrated in about 4 hours.
Try them in hot and cold water. Try them in soda, in ginger ale. Add some salt. Experiment. Add different amounts of water and see what happens.
Spider balls are reusable: once they dry out, you can rehydrate them. You'll have hours and hours of fun.
