Water Beads

Water Beads

4 total reviews

These tiny beads are made of a super absorbent polymer that can soak up a surprising amount of water. Plus, since they are almost entirely water when fully absorbed, they have the same refraction index as water and become invisible.  

Put in your potted plant’s soil to avoid over-watering. Create your own diapers. Fill a vase and put something in the middle to create interesting illusions. Or just enjoy the squishiness.

This 25mL tube goes a long way. And they can be dried out and reused. These beads are clear so you can use food coloring to create any color you want. 

These 3mm dry beads expand to about 40mm (1.5") in diameter.

For scientific demonstration. Do not eat. Keep out of reach of small children or pets.
