This video teaches us how to prevent those pesky paparazzi from invading our privacy. It suggests buying a pair of safety glasses that have lights attached at the sides. Then, remove the lights, and replace the existing resistors with higher-powered ones, and the lights with infrared LEDs. When the press tries to film you while you're wearing these at night, the cameras will see bright, menacing lights where your face should be. This how-to is presented as a joke, but it would be hilarious to see celebrities employing this tactic.
