After a query on Twitter, the US Geological Survey has been forced to warn against roasting the spongy sweets over lava spewing vents in Hawaii. The island's largest volcano, Kilauea, has been erupting since early May.
The US Geological Survey (USGS) on Wednesday cautioned people against roasting marshmallows over an erupting volcano in Hawaii.
The warning came in an exchange of tweets with a curious islander, who wanted to know if it was OK to bake the sweets over lava from Kilauea "assuming you had a long enough stick."
"Erm… we're going to have to say no, that's not safe. (Please don't try!)," the USGS said.
Volcanic vents, the openings in the ground from which lava comes to the surface of the earth, also discharge large quantities of gas, some go which smell like rotten eggs.
The unpleasant smells would also ruin the taste of the marshmallows, the USGS warned.
The agency has issued a stream of public service announcements since. The eruption is not expected to end any time soon.
The ongoing volcanic activity has destroyed more than 70 homes and forced about 2,000 people to evacuate.
