This little thing is soooooo simple to make but can land you a lunch detention really fast! It makes a high pitched scream that will kill anyones hearing for at least a minute or two depending on how close you are. All you need is a scrap piece of paper.
DISCLAMER!!!!!!! If you or one of your buddies looses their hearing from this thing, I ain't the one you should point fingers at.
Step 1: Tear Off a Piece of Paper
The title says it all, tear off a rectangle of paper, any piece of paper.
Step 2: CREATE CHAOS!!!!!
Now hold the piece of paper in your hands and pull it tight, put the clean edge (not the torn edge) close to your lips and blow. After a while you should hear a high pitched annoying death scream, that means its working!!!
