USB Fish Bowl Light

Make a USB-powered light for your beta fish bowl! Trace the rim of the fish bowl onto a thin piece of wood and cut out a half-circle piece of wood. Drill a hole through the wood and attach the light bulb through the hole. Cut off the end of any USB cord and wire the USB cord and light fixture to a circuit. Tape the piece of wood on top of your fish bowl and plug the light into your computer.
