Question

So my chemistry teacher did this experiment and he didn´t tell us how he did it! He had salt and pepper and another subject in his hand. When he snapped his fingers there came a little bit of light and smoke after it, im wondering if you know what subject it is?

Answer 1

Enough to experience a mixture of red phosphorus and potassium chlorate (salt and pepper) in half a match head. On a dry finger with a piece of paper placed a grain mixture (no more than a match head), then another finger produce sharp friction (make a click). If the fingers were dry, there was an explosion, momentarily visible flash of yellow flame. For mixing using crushed separately red phosphorus and potassium chlorate salt. The mixture can be mixed with a pen on a piece of paper.
