For those of you that don't know who The Engineer Guy is, his name is Bill Hammack and he's made it his business to pull back the shroud of mystery from the world of science and engineering. He's done so through over 300 radio pieces and a bevy of videos, like the one featured above, that attempt to breakdown how things work. For his latest feature, he looks to explain how data gets sent all around the globe via fiber optic cables. Trust us, the presentation won't go over your head: it involves a bucket of water with a hole in it and a laser pointer.
