Climbing the wall like Spider-Man might not be too far off, as scientists have come up with a high-tech material that is super-sticky.
They looked at the way geckos cling on to surfaces like glass, and copied the little lizards' climbing technique.
The material, called Synthetic Gecko, has millions of tiny mushroom-like hairs that grip on to things.
It could be used to patch up holes in air-craft, or, excitingly, to make a special climbing suit.

However, the team say they haven't got the material perfect yet.
"The material we have made so far will hold a family car to a roof, or an elephant if you wish" says Dr Sajad Haq, one of the team's top scientists.
"We're not quite at the level of mimicking the sticking power of the gecko."
