- Compress the air inside the tube using the plunger. Cotton at the bottom of the tube will ignite when pressure is increased rapidly.
- Use a very small piece of cotton – almost as small as possible.
- Can use paper as well.
- Same process as to how a diesel engine works.
- This also demonstrates the need for oxygen to support combustion by showing that re-ignition will only occur if the piston is completely removed to allow a fresh supply of air.
- The apparatus can also be used to demonstrate cloud formation.
