So some dude built a phaser. Like, a real one. From bits of a Blu-ray player, an old Playmates phaser toy, and some other stuff. I don’t think it could kill anyone, but it would certainly stun them if you shot them in the eyes with it — since they’d be painfully blinded, possibly for life. However, it can certainly kill the fuck out of some balloons, as this demonstrative video shows. You can read about how he made it here if you want to murder some balloons yourself. and if we ever find a planet inhabited entirely by balloon people, we are fucking set.
