How does glue work?

2 Answers

When liquid is added to an adhesive, it becomes glue. When the glue dries over a surface, it hardens, causing the molecules to stick together. On the other hand, tape is made from mixing rubbery material with adhesives. It doesn't harden like glue, and its bonds are weaker.

It works by bonding. Enzymes in the glue work to adhere itself to a foreign matter. There are natural glues also. The substance that perriwinkles or limpets secrete on rocks in the ocean is a natural one
