In tech we learned about glue, and I know your thinking there is nothing to learn about glue and honestly thats what I thought to. Well, did you know that there are gluing techniques that help the glue dry faster, I know it’s crazy. Did you also know that there is a cure time for glue neither did I, all of this stuff actually leads back to 7000 years ago when caveman wanted their cave paintings to last longer. What the cavemen would do it use animal remains and add them to their pigments for the paintings and boom they would last longer.
