Is it safe to eat marshmallows toasted over volcanoes?

A man has contacted the US Geological Survey to ask a very important question: can you toast marshmallows over a volcano vent?

Presumably inspired by the lava flow in Hawaii at the moment, Jay Furr contacted the USGS’s Twitter account to ask his all-important question, and received a prompt and interesting response.

In short, don’t do it.

So what happens if you mix sulphuric acid and sugar? This video from Home Science shows the reaction in action.

Bravo.
