🎧 What this episode is about:Using high-speed cameras, scientists discovered that popcorn pops at about 180 degrees Celsius. The release of water vapor makes the popping sound, while a newly formed "leg of starch" pushes the popcorn up to leap into the air. This episode explains how popcorn bursts open and jumps within just a few hundredths of a second.
