Here’s a fun gadget, to keep yourself amused in the office, the shocking pen.

Place this pen on your co-workers desk and wait until they pick it up, as soon as they press the top of the pen, they will create a circuit that creates a small magnetic field, which then simulates an alternating current and provides relatively high voltage to the depression point on the thumb.

The pen doesn’t actually work, it is still a fun gadget though that is bound to bring a smile to your face when one of your co-workers or friends picks it up, just make sure you don’t leave it on your bosses desk!

The shocking pen is available to buy online for $5.99 from Think Geek.
