Never try to put out a flaming pan of hot oil by pouring water onto it – the result will be an instant torrent of boiling oil and water, guaranteed to burn the unwary!

Something similar happened during the eruption of Caldera Blanca which turned out to be one of Lanzarote’s few hydro-magmatic volcanoes. When its boiling hot magma encountered water on its way up to the surface, unlike the pan with its flash and a spurt of a of hot oil and water, in case of Caldera Blanca there was a colossal explosion which scattered thousands of tons of rocks for hundreds of metres, resulting in Lanzarote’s largest crater.
