What if you just want one kernel of popcorn? Then all you need is a blowtorch and a hairdryer. This film by Zita Bernet and Rafael Sommerhalder, under the name CRICTOR, shows us how it’s done. If you’re interested in the physics, this is an example of the Coandă effect. The rest of us just think it’s pretty neat. If you prefer to oil-fry your single kernel of popcorn, that will take a little longer.
