Gianormous Squishy Crystals

This week for our science experiment we made Gianormous Squishy Crystals.... the girls loved this fun project. You will need: a teaspoon of polyacrylamide crystals, a test tube (or glass) and some warm water. To start the project put the crystals in a test tube or glass and add 5 ML of warm water... put it aside for 15 minutes.... repeat until the water is no longer absorbed (we did ours for over an hour and they got huge!!)

After putting in a Teaspoon of polyacrylamide crystals, we added in 5 ML of warm water and set the test tube aside for 15 Minutes...After 15 minutes-
Adding 5 ML of warm water to the forming crystals
After 45 Minutes-
Although the crystals appear to be hard...they are actual soft and squish-ish...The girls had fun playing with the crystals. I had them try and break them apart, bounce them, slide them and squish them around.
The girls found that they were slippery, squishy and hard to break...bounced great...

Are those the same crystals from the garden section - used to keep arid lawns green?

I'm curious what those crystals are as well. At first I was thinking diaper stuffing, but it doesn't act like that at all.
