Company execs say they're working on a real-life ray gun which uses femtosecond lasers – light pulses that last less than a ten-trillionth of a second – to carve conductive channels of ionized oxygen in the air. Through these channels, Ionatron's blaster supposedly sends man-made lighting bolts, frying anyone unfortunate enough to step into their path, up to 800 meters away.
