Crush It! with Pressure
This episode of "Science It Up!" from the Little Shop of Physics shows how pressure can be used to crush objects. Atmospheric pressure is very strong! But how can we see just how strong it is? Let’s crush all kinds of things, just with air pressure! Marshmallows, soda cans, paint thinner cans, and to cap it all off, we’ll even crush a 55-gallon oil drum. Don’t miss it!
