Certain audio frequencies bring back certain memories. If you play the right song, it can take you back to a specific point in time. Scientists at Delta University tapped into this phenomenon and, by mixing certain pitches and tones, created an audio file that can transport you back to your most emotionally unstable point in the past. For some, it is infancy. For others, seventh grade.

To test their theory, this track was played over the loudspeaker while several students were taking exams at a frequency so high it was barely detectable. Several things happened. Some students crumpled their paper up in frustration. Others were found crying on the floor. Still others began to argue among themselves or with the teacher.

When one student flung themselves out the 10th story window, they had to close the project for good. However, the track was leaked onto the web and can now be found in the darkest corners of the internet. Listen… if you dare.
