Lol — Sience Lessons

Marshmallows are full of tiny air bubbles trapped in a gelatin-sugar matrix. Lower the surrounding air pressure (like in a vacuum), and the air inside the marshmallow expands rapidly. When you let the air back in, the pressure crushes the now-weak walls. This is Boyle’s Law in action: volume of a gas increases as pressure decreases (at constant temperature).

So, in the spirit of learning through laughter, here are three real “sience” moments that actually taught us something valuable. What happened: A middle schooler put a marshmallow in a vacuum chamber. As the air was removed, the marshmallow grew to four times its size. Then, with a dramatic pop , it collapsed into a sticky, sad mess. sience lessons lol
