Gel balls -
It doesn't say how long to soak the little balls, although the box says they quickly grow. After about 6 hours the gel balls were about the size of very small marbles. We couldn't tell when they had stopped growing since it was so slow. It says to dry them off but they are gel and don't really "dry". They bounce a little but nothing great. It was a long wait for not much excitement. There's nothing in the package that explains what science is involved.
