Cosplaying is one thing. Creating actual, working superhero weaponry is another.
Not content with the various official Nerf replicas, a YouTube user going by the handle AnselmoFanZero has created a working Iron Man gauntlet that fires off an actual rocket. Not a replica, not a toy, a real live rocket. (via io9)
Also, a laser. A freaking laser.
See it below:
As you can see from the user's channel, this isn't the first time he's created a working prop like this. However, like a good magician, he refuses to reveal his tricks, so if you're looking for a tutorial or plans to create your own you'll be disappointed.
