What are Spider Balls and why do we call them that? 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- just like real spiders! Control the range of size by adjusting the amount of water you add. Sure to provide endless delight and days of fun! They slip, slide, and explode. Put them in hot and cold water, throw a few in ginger ale. Watch the effervescence in wonder as Spider Balls hydrate and fizz and foam. Add salt to Spider Balls and watch the effect in awe. Leave a few hydrated Spider Balls out, and watch as they return to their original size. For more awesome polymer science and colored growing balls, check out our Glowing Spit Balls.
