Moisten the inner rim of the suction cup. You can do this by wetting your finger under running water and rubbing it lightly it beneath the suction cup rim; don't get it too wet. This moisture helps the suction cup adhere more readily to a surface.

4
Press the suction cup onto the window or other smooth surface you want it to attach to. Make sure you press it down all the way against the surface.

5
Release the suction cup slowly. This creates a vacuum effect inside the suction cup, allowing it to adhere. If it shows signs of releasing its grip, press it to the surface again until it stays fast. Give it a gentle tug to make sure it is holding tightly.
