Undeniable Friday
Friday, August 04, 2006
It's Undeniable Friday! Every Friday, in addition to an odd little factoid, UndeniableFacts.com gives you a fun puzzle, illusion, or activity to enjoy and share.
Today, an illusion.
This illusion is called "Humming Bars". Here's how it works:
Hum in in as low a falsetto as you can, just high enough to keep your voice from cracking. As you continue to hum, stare at the image. You should see the black and white bars begin to scroll across the image. If you are right handed, the lines will scroll to the left. If you are left handed, they will scroll to the right.
Note: at first you may find it very difficult to hum at just the right pitch. Try varying your tone and volume. At the correct pitch, if you relax your jaw, your teeth should buzz against each other.
