All you need is a bottle of shaving cream and a box of corn starch. This was enough for two tubs of this wonderful, fluffy stuff! We poured about half the box of corn starch in each tub and then just squirted the shaving cream into them. We used the entire bottle between the two tubs. The incredible thing about this is that after a bit, it's moldable! I love the Ooey Gooey Lady!
