Stopwatch

Of the many items that I carry, one that is a favorite is a stopwatch. That is because it is affected in a strange way by an HDR. Also, I have seen it affected by a plasma ball which is similar to a Tesla coil. It is important to note that most devices around an HDR are going to manifest anomalous properties, such as the stopwatch starting and stopping and even blinking in and out. This is part of the high strangeness index of paranormal phenomena that accompanies these devices.
