Imagine the Reaction When Lava Met ice;Photo
So did the guys from Outrageous Acts of Science – so they got some lava, got some ice, and started filming.
None of them predicted the result.
It looks at first as if the lava is bubbling, but that’s not actually what’s happening.
‘The lava is so hot than when it’s poured onto the ice, the ice instantly turns not just into water but straight into steam,’ explains nuclear chemist Alistair Linsell.
‘This steam has to escape so it bubbles through the lava, so while it looks like the lava itself is boiling it’s actually the steam being produced that is trying to escape,’ adds materials chemist Sujata Kundu.
The cooling lava then traps the bubbles inside the rock.
‘It’s kind of like a natural form of glass-making,’ says Linsell.
According to Linsell, the steam is the reason that the lava flows and doesn’t just burn straight through the ice. It forms a bed directly under the lava, creating very little friction.
