Long lines, being patted down, and having your hands swabbed don’t make for a wonderful day, but Michael Aranda explains the machines you encounter in airport security and the science and technology behind them.

Want more SciShow in person? We’ll be at NerdCon: Nerdfighteria in Boston on February 25th and 26th! For more information, go to http://www.nerdconnerdfighteria.com/
