How do you make orbeez small then big?

To make Orbeez small, simply place them in a dry area where they will naturally shrink as they lose moisture. To make them big again, soak the dried Orbeez in water for several hours, allowing them to absorb the water and expand to their original size. The process can be repeated multiple times, as Orbeez can expand and shrink effectively. Just ensure to use clean water for soaking.
