Mini Invisible Marbles - Bulk (approx. 800)
When you put these amazing polymer beads in tap water they start to absorb the water. After about five hours they have absorbed SO MUCH water they are more water than plastic and so they appear invisible in the water. Amazing! There are approximately 80 per pack. Try growing them in water with food colouring, what do you think will happen?
