DIY USB-Powered Fish Tank
Make a fish tank that connects to your computer! Find a large plastic container, such as a candy jar, remove the label and attach rubber feet to the bottom of each corner. Drill holes in the bottom of two CD cases, insert LED lights through the holes and wire the circuit to a switch and USB cord. Use double-sided tape to stick the CD case shut and attach the CD cases to the lid of the candy jar. Decorate your aquarium and plug the USB into your computer.
