I made it a couple weeks ago but it’s something like… Mix1 bottle of clear Elmer’s glue and1/2 cup water. Add food coloring, glitter, etc as desired. Add1/2 cup liquid starch. Mix. The end. It seems to be better after sitting a day or so.
It’s not new at all, it’s essentially Gak from the 90s. I made it with my children (and unknowingly posted a photo to Instagram before reading this article, who knew). Homemade Gak. And I can remember having Ninja Turtle Ooze before Gak existed. This is not new, internet. Chill.
