How to control light with water

 

By: Physics Girl

Originally published on Dec 22, 2016

How fast is the internet? How fast can we send data? This easy DIY experiment allows you to control light with water! Drill a hole in the bottom of a 2 liter bottle, fill the bottle with water allowing the water to stream out the hole, and a shine a laser on the other side so it comes out the hole and follows the stream of water! Just like fiber optics, the laser beam gets bounced around, but stays within the stream. Controlling light in this way gives up the ability to send information MUCH faster, as opposed to sending a postcard via snail mail!

When you mix red and green, what do you get? White light is all of the colors, right? So, how do computer screens show you every wavelength of light? Or do they?

Jellyfish are mesmerizing and beautiful and I have no idea how they work. So I went behind the scenes at the Monterey Bay Aquarium with my new friend Tommy to learn all about them. I saw some things…

Why are we in Monterey? PBS and BBC are teaming up to bring you an incredible LIVE nature broadcast direct from Monterey Bay, California called BIG BLUE LIVE. In late summer, thousands and thousands of ocean animals come together here, in one of the richest ecosystems on Earth. We’ll be bringing you a week of videos direct from Monterey Bay all about this incredible place and the biology it holds.

Big Blue Live airs nightly on PBS 8/31-9/2 at 8 PM ET
Big Blue Live airs on BBC One 8/23 (7PM), 8/27 (8 PM), 8/30 (7 PM)
