Oscar-nominated physics, putting the jump into popping corn and more


By Tushna Commissariat

There is nothing quite like a bowl of hot, buttery popcorn – and it seems as if even physicists are enthralled by it as they dig into the pops and jumps of this tasty snack. A recent article in the New York Times caught our attention this week, as it talked about how a French research duo used high-speed video cameras and a hot plate to see just why a kernel of corn not only pops, but also leaps up as it puffs. The team found that as the kernel’s hull is breached, we hear the popping sound and this is swiftly followed by the jump that happens when a puffy bit of the inside pushes out and makes the corn jump, a bit like a muscle twitch. Take a look at the lovely slow-motion video above of individual kernels leaping about like perfect puffy ballet dancers.
