Rainbow water beads, an easy Science experiment or great for sensory play. Our water beads are made from a safe, non-toxic polymer which expands when in water. Children love the feel of these balls with their slippery and bouncy nature.
Super-Absorbent Jumbo Water Beads will soak up 100x their own weight in water so one 20g pack will fill a 1 litre bowl!
20g= approximately 18 balls.
