Why does a suction cup stay on the window?

When you stick a suction cup on a window you force the air out of the suction cup and you create a high pressure vaccume keeping the suction cup on the window.

A suction cup when pressed onto a clean window sticks to it because?

Science, baby!!! Because when you push it agains the window, it pushes some of the air out along the edge. Then you release it returning the volume close to that of what is was originally and reducing the pressure in the suction cup. The greater pressure in the atmosphere pushes the suction cup to the window with enough force to make friction on the edges of the keep it from sliding around and to keep it against the window. Suction cups wont work in space because there's no atmosphere.

Why doesn't a suction cup hold to a window screen or to a grate?

Because neither the grate or window-screen are smooth surfaces. A suction cup (or similar device) needs a smooth, non-porous surface in order to form an air-tight seal.

How do suction cups work?

When you squeeze the cup against the window, you squeeze out the air from under it. Then the elastic plastic or rubber that the cup is made out of tries to return to its original shape. This causes an area of lower pressure under the cup, and the higher external atmospheric pressure pins it to the window.

Who invented the suction cup?

J.W Greene

Why are suction cups more effective on smooth surfaces than on rough surfaces?

Because rough surfaces prevent the edges of the suction cup from creating a seal, which a suction cup needs to function.

What will happen if air enters the inside of a suction cup?

The suction cup will lose its attachment, unless it has an additional adhesive. Suction cups attached to a surface are held there by the pressure of the outside air, which is higher than the pressure under the cup. The suction cup is trying to return to its uncompressed condition, and pulls away from the surface, reducing the pressure under it.

How do I mount a Magellan GPS unit in my car?

To mount a Magellan GPS you have to simply place the cup onto the window and press down firmly. This will allow the air in it to escape and suction onto the window. It is very simple to do.
