German innovator Patrick Priebe has long established himself as the world's foremost creator of amazing DIY laser weapons, and this reputation continues to be enhanced with the release of this electrothermal cannon watch.
This wristwatch was inspired by various James Bond-based video games, in which players are required to shoot out light bulbs in order to be able to move through enemy territory without being detected. This may be the first weapon created specifically to destroy light bulbs, although it could probably wreak damage to people as well.
All you have to do is press a button that causes a 350-volt capacitor to draw power from an AA battery or a supplied button cell. Once the charging is done with, pressing a second button creates a high voltage arc that causes the capacitor to blast heat and pressure.
The end result is an awesome wearable cannon watch that lets you blast light bulbs and other undesirables.
