Donna

I would not think it was a joke. Having taught chemistry for over 40 years I have seen many "interesting" activities permitted by teachers. I would discourage her from this activity. Nor would I demonstrate this by using my own hand. Students get ideas and want to try it on their own and the more adventurous of them will try it with different substances. It would be better to demonstrate by using a paper towel wetted with alcohol.

I do one demo called "fire underwater" [ethanol on top of conc. sulfuric acid and some potassium permanganate sprinkled into the cylinder. After observing the sparks and the noise I empty the cylinder into a sink and behind a shield. The sink catches fire and we discuss why it burst into flames]. Experience has taught me to have the shield and keep the volume of alcohol limited.

So there are many safer demos to illustrate almost any phenomena in chemistry.

collective scream! can't they watch the videos on you tube & just realize its not such a good idea? what would be the purpose or scientific rationale for doing this?

I don't think you could print my initial response. Please strongly discourage this activity.
