Recipe Notes


Use immediately to play- similar to moon sand. Will dissolve immediately in water

Cover and let sit for four hours on the counter. It will expand immensely. Play dry or on side of the tub.

It’s slightly sticky, can be rolled and molded. It can be broken apart.

Gets hard when left on the counter but can still be squeezed. Takes longer to dissolve in bath.
