Air pressure and change of state
I like a lot of the Steve Spangler videos, but this has to be my all time favorite. It takes the can crushing demo to a whole new level. He crushes 55 gallon drums! It has the can demo at the beginning so show this after any in class demo. You don't want him stealing your thunder. This video is 14 minutes long. I think it is worth the class time, but if you want a shorted clip the link to a 2 minute video is below.
Draw a picture of the forces acting on this can. Draw a picture of the molecules in the can before the warm water and after.
