That stuff is so cool, and so easy to make.. it's just a matter of getting the proportions correct. The cool thing to do is to make some in a small bowl and let your finger/hand just slowly sink in it. Then when you go to pull it out quick, you can't.. You have to work it out slowly again.

Fun stuff to mess with in a kitchen laboratory.
