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.

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.
