[everett] sent in his final project for his mechanisms class. In an attempt to create his own bolt on X gene, he built a wrist mounted hand activated flame thrower: The Pyro System.

Quick disclaimer: Don’t try replicating this one! If you want to skip the movie clip, skip 33 seconds into the video.
