Fiber Optics are an amazing engineering achievement, they help us communicate with one another across vast distances, additionally, they help us send information, and light to where we need. Trying to explain how they work is as hard as solving an algebra equation by chewing bubble gum. That is, unless you are Bill. You probably know him as “The Engineer Guy” but Bill is probably the best teacher in the world, and is considered by many to be the new Bill Nye the Science Guy, he’s able to simplify the hardest of subjects into it’s simplest forms. You’ll pretty much learn everything you need to know in 5 minutes or so.
In this video, Bill uses a bucket of propylene glycol to show how a fiber optic cable works and how engineers send signal across oceans our massive oceans in order to keep us connected with each other.
