Ok guys, here we have a brilliant recipe for lightbulbs that explode when you turn them on, potentially sending burning hot shards of glass flying towards your face.
Lightbulb (100 watt)
Get your drill and drill a hole in the lightbulb just below where the thread starts. Now pour the gunpowder into the hole, and make sure to use enough that it touches the filaments inside. Now, make sure the light is off, and screw in the lightbulb as normal. Now make sure not to turn it on, or you may end up with a shredded face. Try inviting your least favourite government official around for dinner. Try not to be in the room when he turns the light on. :P
