My eldest son is very into science right now and he loved this (no kool aid here in Australia, so I left it out). Thanks for posting.
We left the kool-aid out of it because I'm a lazy mom and didn't want to deal with any stains, but this was SO SO SO cool! We saw it on Ellen and I wanted to try it with the kids. I did have to play with the consistency, but it was awesome. The picture I took, my son just hit it hard with his fist and my daughter has her hands sunk it so you can see how weird this stuff is. We had a BLAST! Thanks for sharing.
