Just add water and watch the Water Marbles grow in size! This listing is for our single colour Water Marbles - perfect for sensory learning. Once grown, you can keep your Water Marbles in an airtight container for weeks or they can be rehydrated once they are dehydrated!
Our Water Marbles are biodegradable and each bottle contains approximately 13g of Water Marbles. All our Water Marbles are packed right here in Australia.
Please note that this contains small parts and therefore, should be kept out of the reach of children under 4. The marbles present a choking hazard and should not be consumed. Please supervise use at all times.
