How Super Glue Went From Military Tool to Emergency Room Hero

Super Glue

Super glue: it’s tiny, it’s sticky, and it’s way more powerful than you think! In this video from Veritasium, host Derek Muller takes you on a fun journey through this accidental wonder of science. Originally invented in the 1940s as a clear plastic for gunsights, it wasn’t long before its incredible sticking power was discovered—and yes, it works on skin too! How? Well, when it meets water, it forms strong polymer chains that bond almost anything—except certain plastics (sorry, plastic toys). You’ll learn why this stuff can hold thousands of pounds, why it’s used in emergency rooms, and how to get it off your fingers without drama. It’s not just about sticking things together—could super glue actually help solve plastic waste? Watch below!
