Welcome to the amazing science of superabsorbent polymers! Slippery-smooth fun to put your hands on and a great learning tool as well. Grow a treasure trove of colorful, squishy crystals just by adding water. You'll also discover the secrets of the amazing substance that scientists call superabsorbents and learn about where real jewels come from.
As one of the top online toy retailers, we have access to unprecendented quantities of product review data. One of the key ways that we use this data is by associating our products to the specific ages and genders of the kids who are playing with them. Whereas most retailers must rely upon manufacturer suggested ages (i.e. 3+), we take actual customer usage and share it with you here so that you can choose the perfect toy or game.
But how does this help me? You can use these graphs as a general measure of it's appropriateness for a given age and gender. While this information is generally accurate, it should not be used as an absolute answer. For instance, many dinosaur toys are purchased for boys, however, that doesn't mean that it's inappropriate for a girl who happens to like dinosaurs.
NOTE: The orange color in the charts above indicate ages that are LESS than the manufacturer suggested age. Please purchase at your discretion if your child is younger than 5 years of age.
Facinating & fun!

It takes a while for the jewels to grow to a size that is fun to handle, so next time I'd probably put them in a bowl of water the night before, but once they get to marble size they are really fun to play with. Everyone in the family had fun with them, and it's amazing how they keep growing. After you're done they will dry out over a few days & be ready to use again.

I bought these for a Magic in Science class camp for 3 - 6 year olds. We soaked these over night and where all amazed with "balls" and squares that appeared the next day. Some were so clear you could not see them in the cup. The balls bounced, the jewels went splat and broke. Some kids smooched them. Parents were impressed and asked where I got them. Should I give up my teacher's secret???
