Sadly, this is probably just a camera trick involving smoke and
LED lights.  But what if a man actually built a working Star
Trek phaser? What if he used it to pop balloons? What if he
brought it to a bank and took everybody hostage? What if he used
all of the money to build more Star Trek devices, like a working
spaceship with its own holodeck? What if his evil, bearded twin
from a parallel dimension came out and challenged him to one-on-
one combat for rulership of the universe? What if he won? What
if he turned us all into tribbles?  Guy Builds A Star Trek
