Easily one of the coolest sci-fi weapons of all time is the ZF-1 from The Fifth Element. If you’re not as familiar with the Luc Besson sci-fi film starring Bruce Willis as you should be, it’s the weapon that Gary Oldman demonstrates for his alien crime partners who are trying to steal the elemental stones for him. The gun has a rocket launcher, arrow launcher, net launcher, flamethrower, ice blast, a feature that allows every bullet shot to hit the same target, and of course a self-destruct button. It’s been an object of desire for Mythbusters co-host Adam Savage to build his own for years, and now after 17 years of work, he’s finally completed it.
