Water Jelly Crystals
These amazing pebble-sized polymer crystals mysteriously grow.
Usually ships out the next day.
Recommend for 6 to 7 years with adult supervision.
Deal of the Day
These amazing pebble-sized polymer crystals mysteriously grow into huge pieces of gel-like material when you add water. In fact, these crystals absorb 150-300 times their weight in water! Because of their incredible thirst, they're even used to reduce the amount of water needed to water crops and gardens during years of drought! Included with each package of crystals is a science activity guide, with lots of fun ideas for science projects. Water Jelly Crystals are an example of amazing Hydrogels... superabsorbent polymers that are saving the environment. Ages 6 and up.
What's included?
- Water Jelly Crystal polymer in your choice of container size
- Science activity guide
How does it work?
Soak the crystals in water and see how fast they absorb water! In just a few minutes you'll have a huge bowl of icy looking crystals, only they're not cold! Dry them out on a paper towel, and you can use them again!What does it teach?
Discover how polymers perform very important functions in everyday life. Sometimes referred to as Hydrogels, they're used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, superabsorbent crystals are a great way to teach kids about color and light!Product FAQ

Material Safety Data Sheets (MSDS)
Most teachers are required to obtain an MSDS on every chemical in their classroom. Without proper training, however, MSDS information can be quite intimidating and could possibly lead a person to the wrong conclusion about the safety of a product. For example, would you consider water to be a safe chemical? Sure it's safe... it's water! But try reading the MSDS on water and you might be surprised. "FIRST AID: Call a physician, seek medical attention for further treatment, observation and support after first aid. Inhalation: Remove to fresh air at once. If breathing has stopped give artificial respiration immediately." Sounds frightening... and it's just water! If you request an MSDS on any product, make sure you understand what you're reading beforejumping to any conclusions. Any chemical can pose safety concerns (yes, even water). The best advice we can give parents, teachers or any adult supervisor is to read and follow the directions carefully. Look for phrases like "non-hazardous" or "not expected to be a health risk". If you have any questions, pick up the phone and call. Most importantly, if an accident happens, seek help immediately.

Watching Things Grow in Water is Always Cool!
Karri - February 26, 2013
My 6th grader needed to do a project for his Science class that had to be presented in the science fair. When we found this site and this product he said, "That's the one!". He was excited to have a project with so many practical uses and the mushy water gel stuff is just cool! Not only did the water jelly crystals capture his interest and solve our need for a project idea, it got his imagination going!! These little crystals are worth their 3X growth weight in gold! |

STEM Student Expo
Thomas Hollen - March 9, 2012
The jelly crystals were a hit. I had made up some colored ones, but had a a five gallon bucket half full of expanded crystals. I put a sign in from of it that said "Warm Ice". Everyone had to stick their hands in it. I got a widw variety of reactions from WOW to OOOUU. I gave several teachers samples and the catalog I had with me. It was a real hit and brought a lot of students to our table. |

mad scientists at work
Phyllis Mueses - September 28, 2011
My 4th grade "mad scientist" chemistry club really loved observing how the jelly crystals reacted with water and various other liquids. They are still observing how long it takes for the water to evaporate for the crystals to return to their original state. This stuff really has them excited about working like a scientist! |

Very Cool!
Katie - April 14, 2011
I ordered the jelly crystals for a color mixing project with my students. The tiny little crystals (size of rock salt) grew to giant squishy chunks in just an hour. I left them overnight and they grew even more! I even used some of them in my garden to help regulate water in my potted plants. Very cool! I will order again when I use them all up! |

We love to color these crystals with each child's customized color after they create a color with the color tablets. |

Have been looking for this!
Misty - November 18, 2010
I bought some of these in the early 90's and have grown several plants in the same batch. Finally, I found SSScience and am able to get more! No more dirty potting soil for my houseplants! And the kids in my summer program are going to be amazed! I can't wait to give them all cuttings and let them take home their own crystal "earth". |

Best stuff ever
Liz B - September 23, 2010
Ive used these for years. Its simple and easy for my 1st graders to do on their own. Great for measuring. I also use steve spangler's "pinch and mix gel colors" and mix those together to create different colors for our crystals. I get the 5lb bag and it lasts for months. |

Water crystals
Kimber - May 19, 2010
These water crystals are great for planting new plants to making water crystal rainbows in test tubes. My only complaint is that it takes an hour for these to grow. |

My brain popped with happiness!
Shay Williams Shreveport, Louisiana, USA - November 28, 2009
Those jelly balls are so awesome! My mom was so shocked when I told her what a polymer was! I would also like to say thanks for the snow; my 4yr old cousin enjoyed that the most. Your products just leaves me speechless, and there is no word that can describe the happiness and enjoyment that I had with your product!!!!!! ----Shay---- |
