What makes some substances sticky to touch compared with others?
In: 8
Imma try this, although without much knowledge: Some materials have a rough surface and are solid, like unfinished wood. Not sticky. Some materials are smooth and liquid like water. Will stay on your skin for a bit but also run off. And then I think if you combine a liquid with a fine solid material like a powder you sometimes get a mixture that is semi-liquid and sticky.
So my ELI5 is: By combining materials with different properties.
The sticky substance is only half of the equation though. It also depends on where you want to try to make it stick. Stuff may stick to your hand better than to a teflon coated pan.
