Thanks to a May 4 earthquake, there’s now a volcanic eruption happening on Kilauea, a volcano on the southeast corner of Hawaii’s Big Island. The eruption has unleashed several lava flows, compelling authorities to evacuate the area and tell citizens not to roast marshmallows over the lava. It turns out while a volcano marshmallow sounds delicious, it could actually kill you.

The U.S. Geological Survey (USGS) issued the advisory not to roast marshmallows over lava through its Twitter account after a Twitter user named Jay Furr asked, “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?”

“Erm … we’re going to have to say no, that’s not safe. (Please don’t try!),” the USGS responded. “If the vent is emitting a lot of sulfur dioxide or hydrogen sulfide, they would taste BAD. And if you add sulfuric acid (in volcanic smog, for example) to sugar, you get a pretty spectacular reaction.”

The “spectacular reaction” is the chemical reaction sulfuric acid turning sugar into fluffy black carbon. The acid pushes the water out of the sugar leaving inedible charred fluff where your marshmallow used to be. It kind of smells like caramel, but we certainly wouldn’t advise eating it — it’s not poisonous so much as nasty…. kind of like eating a mouthful of ash.

Here’s a video of what happens when you mix sulfuric acid and sugar:

Also, lava tends to run anywhere between 1,165 and 2,120 degrees Fahrenheit. Which means, even if you had a very long stuck, your clothes could ignite if you get too close. The rubber on the bottom of your shoes could melt off too.

Also, prolonged exposure to volcanic gases can cause you to pass out from lack of oxygen or sustain serious (even potentially fatal) burns.

As it is, the lava has knocked out power and blocked roadways in some parts of the island. So far 35 structures, including 26 homes, have been destroyed by the lava, but no one has been seriously injured or killed.

The Kilauea Volcano has actually been erupting off and on since 1983.
