Clear Acrylic Plastic Suction Cup, also known as a Sucker, uses negative fluid pressure of air or water to adhere to nonporous surfaces, creating a partial vacuum. Clean suction cup and glass area prior to use. Lightly exhale breath onto suction cup surface. Slowly press in center of suction cup up against a glass surface and hold the position for a few seconds while vacuum pressure occurs. Over time vacuum pressure may release so best to occasionally reapply.
