Taming a chemical ghost
Attention! All experiments are performed by professionals. Do not attempt.
- alkaline luminol solution;
- thick paper;
- q-tip, ozonizer.
A q-tip is dipped in an alkaline luminol solution and is used to draw a ghost on a piece of thick paper. The lights are turned off and a stream of ozone is directed at the drawing – the drawing glows blue!
Ozone oxidizes luminol. In the process, energy is released as a blue glow.
A safer version of this experiment is included in the “Chemistry & light” set from the MEL Chemistry subscription
