Superstrong, Reversible Adhesive That Works Like Snail Slime

A new study demonstrates a strong, reversible adhesive that uses the same mechanisms of adhesion as snails. When wet, the material conforms to the grooves on a surface and when dry, the material hardens and fastens itself securely to the surface. “When it’s conformal and rigid, it’s like super glue. You can’t pull it off. But, magically, you can rewet it, and it slips off effortlessly,”
