Gak (Borax-Free)

Gak recipes are abundant, but I had yet to find a Borax-free concoction until I discovered Asia Citro's ingredients. http://www.funathomewithkids.com/2013/07/borax-free-slime-dough.html
We definitely had to alter our quantities to the point where I do not know how much of each cornstarch and shampoo was used! Honestly, I think we never achieved actual Gak consistency, but we made a dough that was extremely fantastic to play with.

It literally melted in your hands, from a somewhat solid heap.
It broke off clean and dry like a piece of chalk.
It can be rolled, cut, caked...you name it.
The best part is it saves for a long time in the fridge for continued use.
Just wet your hands and get down to play time.
