Spiders can crawl up walls into high spaces, why can’t they climb out of the bath?

In: Physics

They can, given enough time, but bathtubs are designed to be smoother and are consistently more wet than even the walls of a shower. That makes it harder for a spider to get up out of the tub, especially before the humans in the home come in and flood the tub with water

Because spiders have some little hooks at the end of their legs. The hooks are what make possibile to climb but this depends from the material. On the bath the hooks have nothing to clinch.

Friction. Spiders can go up walls because they’re not completely smooth like bathtubs. It’s like walking on a normal sidewalk compared to walking on an iced over sidewalk. Uphill.

Imagine you’re wearing socks in your house and you slip over. If you’re on a smooth, tiled floor you don’t have any grip and will fall over. If you’re in a carpeted room, you’ll have better grip. This grip between your socks and the carpet is called ‘friction’.

Although walls seem pretty smooth, they are still a slightly rough surface in comparison to the inside of your bath. The spiders feet won’t have any grip and therefore the spider will find it harder to climb out. This is because there is no friction between the spiders legs and the bathtub.
