There’s more than a bit of playful mischief in the chemistry-themed videos produced by University of Nottingham professor Martyn Poliakoff, journalist Brady Haran, and the rest of their merry cast of characters. The videos—which are available on YouTube and started by featuring each of the elements in the periodic table—involve chemical reactions to please any video-watching wise guy, science geek or not. One shows what happens to a cheeseburger after it has been lowered halfway into a beaker of hydrochloric acid and left for a few hours.
