The popping sound made by popcorn has baffled scientists for decades, remaining one of nature's major unsolved problems.
French researchers say they have finally settled the question of why popcorn pops through a series of high-speed camera observations, sound recordings and the theory of thermodynamics.
They also discovered that popcorn 'jumps' in the same way an animal does.'Popcorn bursts open, jumps and emits a 'pop' sound in some hundredths of a second,' the researchers wrote.
'The physical origin of these three observations remains unclear in the literature.'
As the vapour is expelled, the cavity inside the kernel acts as an 'acoustic resonator' resulting in an audible pop.
