Tape can stick things because it has a layer of adhesive on its surface! The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; In modern times, various polymers are widely used. Adhesives can stick things because they form bonds between their own molecules and the molecules that want to connect things. This bond can firmly bind molecules together.

Because the double-sided adhesive tape has good adhesion, it can be used to make some objects that need to be fixed. Glue some plastic bottle caps or packaging boxes to prevent them from falling; Applying glue to the joint of two objects and then sticking a piece of double-sided adhesive tape will help them integrate better.
