Summary

This Veritasium video explores the history, chemistry, and applications of super glue (cyanoacrylate). It begins with the accidental discovery by Harry Coover in 1942 and its commercialization as Eastman 910. The video explains the polymerization mechanism triggered by water and the role of electron-deficient double bonds. It demonstrates why super glue bonds strongly to skin and other porous surfaces, and why it fails on smooth, inert plastics like polyethylene. The video covers practical tips, such as using acetone to remove glue and baking soda as an accelerator. It also discusses the development of medical-grade cyanoacrylate for wound closure, including its use in the Vietnam War. Finally, it highlights recent research on using cyanoacrylate as a recyclable plastic, addressing the problem of microplastics. The video includes expert interviews, demonstrations, and a clear explanation of the underlying chemistry.
