You see 2 containers, each container has a bulb inside.
The left container with a Clean Air Lamp bulb.
The right container with a normal bulb.
The containers are filled with cigarette smoke. The smoke can't escape!
We light the 2 bulbs.
You see that after seconds the cigarette smoke in the left container starts to dissolve, after 10 seconds the smoke and smell is completely dissolved! The right container is still filled with smoke.
