Therr are many types of glue including: PVA, gluesticks, super glue, etc. Im wondering, why some are better than others and why some glues don’t work at all? The typical school glue stick can sometimes barely glue a sheet of paper to another while some glues can stick buildings together.

Glue can work a couple different ways. In most cases it’s a non-solid material that hardens between the two objects you want glued together, and before hardening it seeps into all the little pores and holes of the material. This is mechanical adhesion.
Some glue is especially effective on certain materials, for example, wood glue is way better on wood than on plastic. This is because wood glue is made with the chemical structures of wood in mind in order to bond at a greater level. This is dispersive adhesion.
Some glues will take dispersive adhesion to the next level by chemically reacting with a material in order to create hydrogen bonds – a particularly strong chemical reaction – to stay bonded. Ever gotten gorilla glue on your hand and had to remove it, and your skin felt super soft afterwards? That’s because it bonded to the top layer of your skin and you had to rip that top layer off to get rid of the glue.
As for the efficiency of the glue, school grade glue sticks are made with a lot of filler and shitty cheap material, so it’s not going to work as well as a wood glue or industrial grade adhesive.
