OOOh, I have an awesome one. Of course, we have one that he (2 y.o.) can make by himself, but I prefer the one that you make in a saucepan. I'll send it in later but it has salt and flour of course. A bit of oil and cream of tartar. Lasts forever

How about gak/flubber w/glue? Every try that? Very cool stuff.
on my way to work but i'll check back and see if you're still needing recipes later
