Physicists have made a recent discovery that just might affect you this Christmas. It seems that when you peel scotch tape off of the roll, it emits X-Rays lasting about a billionth of a second long. no need to be too worried though – apparently this phenomenon only occurs within a vacuum.

When the tape is pulled away from the roll electrons jump from the roll to the sticky underside of the tape. When hitting the stickiness of the tape, the electrons slow down and that is when they emit the X-Rays.

Unless you plan on wrapping your Christmas presents inside your Electrolux, you really have nothing to worry about, but its interesting never the less.
