When Ivan Vanko attacks Tony Stark in "Iron Man 2," Vanko uses lassos while Iron Man tosses repulsor blasts at him. Some day, soldiers might actually lob fireballs at the enemy. Researchers have created ball lightning, which is essentially the same as Iron Man's repulsor blasts.
Using a 600-watt magnetron microwave drill, researchers Eli Jerby and Vladimir Dikhtyar from the University of Tel Aviv created a flaming column, which drills through solid objects such as glass and silicon. When the beam turned away, it pulled the molten material with it and the fiery column morphed into a fireball
. The pulsating flame quivered and hovered in the air for about 10 milliseconds before it was snuffed out.
Similar experiments can be done with a microwave, although we don't recommend it, especially if you happen to be the guy in this video who stores his gasoline in the kitchen.
