Making your own popcorn is one of the cheapest and easiest (and healthy, too!) snacks you can make. When you buy white popcorn kernels in bulk it costs less than $1 per pound. Toss it with a little kosher or sea salt and you’re good to go for a potato chip alternative at lunch or a night time snack before going to bed.
The above slow-motion video of a single kernel of popcorn popping was shot at 6,200 frames per second from the folks behind Modernist Cuisine. They explain that once a kernel reaches a certain level of internal steam pressure, “the kernel is released very rapidly, expanding the starch and proteins into a dense foam that sets quickly.” [via Eater]
