So far as gastronomic creations are involved, they maybe do not get any stranger than mixing a McDonald’s Big Mac hamburger with molten copper. That is exactly what YouTube user Tito4re has done, producing a cacophony of fire, sound and one pretty charred hamburger.
The molten metal appears to bounce off the venerable fast food thing, which some have interpreted as an indication of the almost otherworldly properties of the Big Mac.
If lava unexpectedly erupts into water, the water surrounding it becomes a vapor. This is caused by the huge temperature variation.
In case of the molten copper, it affects the face of the hamburger that is not as hot and somewhat damp. Pouring close-boiling water on the hamburger wouldn’t generate the same effect; the temperature difference between the hamburger would not be high enough to start the Leidenfrost effect.
