Alcohol is highly flammable, and is never to be heated directly with a Bunsen burner. The answer was to use a water bath.

Although an electric heater is safer than an open flame, a water bath is still always used. It makes the experiment much more safe and since the boiling point of ethanol never exceeds that of water there is no reason to not use it.

Well I don't know if an electric heater can be used but I have always seen ethanol being heated in a water bath.

Actually that's the one question I didn't seem to understand. I only had about two minutes when I got to that part anyways.
