Our Water Marbles, or waterbeads are an awesome way to enhance sensory play with MiniZoo model animals. Simply these the colourful marbles to water and you will instantly create a stimulating play time allowing children the opportunity to explore, discover and develop their creativity at their own pace. Once the water beads have grown, you can keep them in an airtight container for weeks, or let them dehydrate and add water later to make them grow again.
