What causes glue to stick?

What causes glue to stick?

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. When the glue dries over a surface, it hardens, causing the molecules to stick together.

What is the source of glue?

Glue can be made from plant or animal parts, or it can be made from oil-based chemicals. The first glues may have been natural liquids that come out of trees when they are cut. Later, people learned to make glue by boiling animal feet, cartilage or bones.
