I’m not talking about like water or stuff like that, I mean like superglue or a glue stick or duct tape or so on.
In: Chemistry
The stickiness of the adhesive is caused by molecular bonds, and its strength depends on how much stress is needed to pull those bonds apart. Every substance contains molecules that have a positive or negative charge. For two substances to bond, their opposing charges need to be attracted to each other in the exact amount of charge. When the glue dries over a surface, it hardens, causing the molecules to stick together.
