AquaBalls are fun to bounce, roll and throw. They will slip, slide and even explode! Let your imagination take over as you experiment with them. Simply fill a cup or bowl with water and add AquaBalls. In less than one day, they will expand to over 200 times their size as they grow to the size of a marble! You can make AquaBalls big or small. The more water you add, the bigger they will get. The bigger they are, the quicker they explode. Smaller AquaBalls will bounce more and last longer. You can experiment with different ratios of water to make balls that best suit your fancy. Let them dry out to use over and over again. To keep them hydrated, store in a sealed plastic bag or container. Store dehydrated AquaBalls in a cool, dry place. Non-toxicEnvironmentally friendlyMade in the USA!
