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...

What a super fun science experiment!!
Are those the same crystals from the garden section - used to keep arid lawns green?
Fun investigations! I like your photos.
That looks fun. What a neat science experiment. I've linked up to your post on my weekly favorites here: http://play2grow.blogspot.com/2011/02/weekly-favorites-for-february-20-2011.html
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.
