Microwaving Light Bulbs Is Genuinely Useful

I love finding new things to put in the microwave. Say, for instance, an incandescent light bulb, which can test your microwave for a number of issues, besides just looking awesome. Even a non-functioning bulb can work, so dig out the dusty old bulbs you have at the back of the closet.

First, find a short juice glass and add some water to it. Put the bulb in the glass like it's a flower in a vase. If the water doesn't cover the metal casing of the bulb, add more water until it does. The water serves two purposes. First, it's very bad for a microwave to be working with nothing, or only very little, inside it. The water soaks up a little of the energy that's going to be bouncing around inside the microwave. The water also covers the metal casing of the light bulb, preventing sparks.
