Hearing practice #4c
I like doing hearing tests and I try to type down what's been said in the video and see how accurately I get the words. I would like you to correct my mistakes, please, here is the video:

A kernel of popcorn pops, obviously, but it also jumps into the air and somersaults, and for the first time 2 French scientists have figured out the physics of that. First, the heart-hole hard hull splits because of the pressure of heated hidden water vapor. The vapor is what makes the pops sound up, then the sudden puffy expansion works like a muscle, vaulting the corn kernel into the air. The researchers have equations for all of this, temperature, force, pressure, so it makes popcorn a very good tool for teaching physics, and it's still tasty. Popcorn, anyone?
[Wow, you did a good job! Some parts are practically "swallowed", one can't hear them...]
