It’s time to have some fun. These amazing water-balls grow up to 200 times their original size. Why would you use these? You can use them for bouncing, throwing (at someone;), and smashing. Yeah, you can’t cure cancer using them but sometimes we just need to have some fun, right? They look like kernels of salt prior to activation but when they are dropped into a bowl of warm water, they’ll grow up to 200 times their original size. Leave them out on dry air and they return to original size.
