What holds a suction cup in place?

How do you make suction cups stick forever?
Make sure both the inside of the suction cups and your window are clean and dry before application.

Do suction cups stick better wet or dry?
Two perfectly smooth, flat, and clean surfaces will form a surprisingly strong bond, simply due to inter-molecular forces. Wetting a suction cup makes it stick better because the water fills in the imperfections, and allows the small vacuum created by the elastic properties of the suction cup to be maintained longer.
Why do suction cups stop working?
In many cases, suction-cup failure occurs when either the suction cup or the surface it’s grabbing isn’t as clean as it could be.
