Instructions
Pour water into the tank that comes in the Magic Marbles kit. Leave about 1/2 inch at the top so it does not spill or overflow.
Drop in any number of Original Magic Marbles from the kit.
Wait 6 to 8 hours for the Magic Marbles to absorb water and grow to their largest size. They start out the size of BBs and grow to a diameter of about 1/3 inch.
Remove them from the water. They will actually bounce, but will burst under high pressure.
Allow the Magic Marbles to dry out. Depending on humidity, this will take another 6 to 8 hours. They will return to their original small size when dry. You can repeat the grow procedure as many times as you like.
