Superabsorbent Water Jelly Crystals

SEE VIDEO BELOW!

These incredible little stones turn into huge water crystals when placed in water. Make a giant crystal vanish like magic! Grow these crystals over 300% their size! You'll get over 500 crystals to turn into tons of squishy crystals otherwise know as "Superabsorbent Jelly Crystals". Grow them, shrink them, color them, even make them disappear! You'll also learn how these crystals can help save water, and help the environment. Makes a great science fair project! These incredible polymers come to life in water and once they start absorbing water they just keep getting bigger and bigger. Comes with a great activity guide with lots of cool science project ideas.

What you'll get:

• 1 Bag of Superbasorbent "Jelly" Crystals.
• 1 Blue measuring scoop.
• Zipper-lock bag to hold the crystals.
• Activity guide with experiment ideas and scientific explanations.

Incredible Science Fun Learning Ideas:

• Tons of amazing science properties are at hand. Proper name for these water jelly crystals are "cross-linked polyacrylamide copolymer gel". Good luck saying that 10 times fast.
• See them disappear in water and discuss water refraction!
• Watch them shrink back to their original size and discuss evaporation.
• Experiment with food coloring in water and predict if they jelly crystal will absorb the water...predict if they will retain their color once they shrink. And if they DO keep their color predict what will happen to the colored mini crystal once you place it back into regular clear water.
• Learn how these crystals help preserve water in the soil, especially during drought conditions.
