US Geological Survey: Please don’t roast marshmallows over volcano vents

People looking to roast up some marshmallows shouldn’t view a volcano as an adequate substitute for a campfire, the U.S. Geological Survey says.

As Hawaii’s Kilauea volcano continues to erupt, a Twitter user asked the agency late Monday if heating up the sugary treat over volcanic vents was safe.

“Is it safe to roast marshmallows over volcanic vents? Assuming you had a long enough stick, that is? Or would the resulting marshmallows be poisonous?” Twitter user “Jay Furr” asked.

“Erm…we’re going to have to say no, that’s not safe. (Please don’t try!),” USGS said in reply, before explaining how the toxic gases associated with the volcano wouldn’t make for an appetizing experience.


“If the vent is emitting a lot of SO2 or H2S, they would taste BAD. And if you add sulfuric acid (in vog, for example) to sugar, you get a pretty spectacular reaction,” USGS added.

However, Furr wasn’t done asking questions.

“Okay, what about roasting hot dogs?” Furr queried, before tweeting, “Stupid Questions ‘R’ Us.”
