Best Answer

A suction cup is named appropriately. The rubber material is formed into a half sphere and once pressed against a solid structure releases air and attaches to the surface.

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.

How do you improve a suction cup?

You can improve suction it by moisturizing it's edges, this makes it stick to something longer and stronger.


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.


Why does a suction cup stick to a wall?

because it is pushed up to the wall by the atmosphere


What happens when you try to stick a suction cup on a rough surface Why?

as we know that suction pump stick on a smooth non-porous surface but rough surface contains pores due to which suction pump is not able to maintain grip with the rough surface.

Do the streamline Nerf darts stick?

Nerf streamline darts do not stick to any surface. They are just a round rubber tip with no suction cup.


Do suction cups stick equally well to different surfaces?

No. How well a suction cup sticks to a surface has to do with how will a seal can be formed on the surface. Rough surfaces will not form good seals compared to smooth surfaces which means that suction cups will not stick as well to rough surfaces as they do to smooth surfaces.


Why do suction cup stick to wet surfaces better than dry surfaces?

The liquid wetting the surface forms a seal that holds atmospheric pressure outside the suction cup. With a dry surface, air can leak through scratches and roughness at the interface between the cup and the surface causing the pressure inside the cup to rise to that of the surrounding air. Once the pressure inside the cup equals the atmospheric pressure outside, there is no longer a suction force to hold the cup in place.


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.


How to Improve suction on a suction cup?

Cut a potato, rub the juice on the suction cup. This really does work. I don't know why.


Would a suction cup work in a vacuum?

No, a suction cup works by forcing air out of the space between it and the surface it's on. No air = no suction.

Using suction.


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.


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.


What is another word for a suction cup?

mounting cup


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.


How do you replace rear window on F150?

The rear window on a Ford F150 is replaced by removing the outer seal and pulling the glass out with a large suction cup. The seal can then be replaced, sealant placed along the edges, and the new glass put in place.
