Great for ooey, gooey color mixing fun! 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?
- 227 grams (1/2 pound) of red
- 227 grams (1/2 pound) of yellow
- 227 grams (1/2 pound) of blue

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 called Hydrogel, they're used in everything from baby diapers to environmental cleanup materials! Aside from their environmental and industrial uses, super-absorbent 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.

Elementary science club
Rick - November 12, 2011
We used these crystals (along with the instant snow and the jelly marbles) in a recent meeting of the science club I host for 5th graders at my school. Kids this age get a kick out of these things, both watching them grow and then feeling their squishiness after they're grown. We eventually put them into half-liter water bottles so the kids could take them home and watch the colors bleed through the layers. |

Hydrogels
Maureen - March 3, 2011
These colored jelly crystals were a big hit at our elementary school science fair. Kids from K-4 enjoyed making rainbows with these gels and learning about their environmentally friendly uses. I would highly recommend as a simple expt for all ages. We have also combined the use of these crystals with the baby diaper expt. |
