Knowing what something is called is a far cry from knowing how it works. That was a lesson the Nobel-Prize-winning American physicist Richard Feynman (1918–1988) often used to teach. So let's forget all about adhesives, acetates, and acrylates and try to figure out why one thing will stick to another.

Now we know that adhesives work through adhesive and cohesive forces, we need to understand a bit more about how those forces themselves work. Let's start with cohesive forces. As you can discover in our main article about the magic of water, water molecules join together with one another because they're not symmetrical.
