Description

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!

Also found this great video by engineer guy who set up the experiment much better than we did:
