Eli Jerby and Vladimir Dikhtyar from Tel Aviv University in Israel have now been able to make lightning balls in the lab using a "microwave drill"
What the scientists then do is pull the microwave drill out of the solid, which drags the molten hot spot and creates a hot drop. The drop then becomes a floating fireball that measures about 3 centimetres across and lasts for some tens of milliseconds. "The fireball looks like a hot jellyfish, quivering and buoyant in the air," says Jerby.
