Epic optical illusion (or "glitch in the matrix") redux

(CBS News) I'm starting to notice a sequel trend starting here. Yesterday we sawthe "human slingshot" from Devin Graham (aka DevinSuperTramp) get an even more fun and extreme redo a year and a half later. Now we get to seeone of the most epic optical illusions (or "glitch in the matrix") ever get the same treatment after a year. You really, really need to check this one out.

Did I just take the red pill? The simply mind-blowing demonstration of science in the coolest way possible was posted by brusspup who writes about his project redux:

Ever since I created the first version of this video a year ago I've been wanting to try it again with more water and better lighting / footage. This is a really fun project and when you first see the results, chances are your jaw will drop. The main thing to keep in mind for this project is that you need a camera that shoots 24 fps.

The effect that you are seeing can't be seen with the naked eye. The effect only works through the camera. However, there is a version of the project you can do where the effect would be visible with the naked eye. For that project, you'd have to use a strobe light.

For this project you'll need:

A powered speaker

Water source

Soft rubber hose

Tone generating software

24 fps camera

Tape.

Run the rubber hose down past the speaker so that the hose touches the speaker. Leave about 1 or 2 inches of the hose hanging past the bottom of the speaker. Secure the hose to the speaker with tape or whatever works best for you. The goal is to make sure the hose is touching the actual speaker so that when the speaker produces sound (vibrates) it will vibrate the hose.

Set up your camera and switch it to 24 fps. The higher the shutter speed the better the results. But also keep in the mind that the higher your shutter speed, the more light you need. Run an audio cable from your computer to the speaker. Set your tone generating software to 24hz and hit play.Turn on the water. Now look through the camera and watch the magic begin. If you want the water to look like it's moving backward set the frequency to 23hz. If you want to look like it's moving forward in slow motion set it to 25hz.

Have fun!
