The Collapsing Train Car

Description:  The collapsing train car can be used as an anchoring phenomenon on a unit related to the structure and properties of matter. The macroscopic implosion is caused by a decrease in pressure within the train car and air pressure crushing the car. To fully understand this phenomenon students must understand what is going on at the microscopic level. This phenomenon can be demonstrated at a smaller scale in the lab using an empty soda pop can (containing a small amount of water) that is heated and then inverted in water.

A railroad tank car demonstration imploding after placing a vacuum on the tank with the vacuum safety valves disabled or removed. If anyone has more of this video or similar videos let me know.
