Science Sunday: How Suction Cups Work

Welcome back to another edition of Science Sunday. We are talking suction cups on this segment today. Most everyone has probably had some experience with suction cups, so we thought we would explain a little bit of how they work. There is no glue or adhesive that helps it to stick to surfaces, so how do they stick so well? It is all pretty simple and comes down to air pressure. Watch the full segment below to learn just how they work, and how much weight they can hold.

There is so much more Science Sunday to explore. Check out the full gallery of segments on our blog: https://ctsciencecenter.org/blog_categories/science-sunday/.
