00:07

The oldest glue in the world is over 8,000 years old

00:11

and comes from a cave near the Dead Sea.

00:14

Ancient people used this glue,

00:16

made from a mixture of animal bone and plant materials,

00:20

to waterproof baskets and construct utensils.

00:23

And for thousands of years after,

00:25

plants and animals were the glue that held human civilization together.

00:29

Today, we have enough types of tape and glue to build and repair almost anything.

00:34

But what gives glue and tape their stickiness?

00:38

And is one stronger than the other?

00:41

Adhesives can be made from synthetic molecules

00:44

or natural proteins and carbohydrates

00:47

like the vegetable starch dextrin,

00:49

the milk protein casein,

00:51

and the terpenes in tree resin.

00:53

In order to work, glue and tape need both adhesive bonds and cohesive bonds.
