The popular Yanny or Laurel test with a horrifying twist!
HOW IT WORKS:
This application looks just like a Yanny or Laurel test. It plays a series of tones at different frequencies and asks the user if they can hear Yanny or Laurel. Then at just the right moment....BAM, a horrific face pops up on the screen with a loud and very scary scream.
GUARANTEED TO SCARE THE SOCKS OFF OF ANYONE!!!.
Headphones are recommend for maximum scare effect.
