Camp fire mug would do it but it would boil out the contents in a moment from the near instantly achieved rapid boil. And not fully evaporated just nuked into steam as it ejects / “explodes” from the cup. Would look a lot more violent then rapid nucleation.
It’s not like you throw the cup straight in though. Just open the door slightly and bring the mug close. The metal will conduct the heat well and considering that water has a pretty decent heat capacity it won’t blow up instantly.
