Bologna Bottle
Description:
The Bologna Bottle has been heated and then the outside has been slowly cooled, rendering it hard enough to drive a nail into wood. The bottle's inside surface, however, has been rapidly cooled, maximizing internal stress. A mineral is used to scratch the inside surface of the bottle, at which, due to the internal stress, the entire bottle shatters.
Physics Concept:
- Modern Physics
- Atomic Physics
- Molecular Models
The demonstration takes about 1 minute to perform.
