CD Case Aquarium
Turn an empty CD case into a fish tank! Carefully cut off the spindle from the center of the case base. Cut out portions of the case base to make windows that will allow air into the aquarium. Cut off the end of a AC/DC wall charger and split the wires. Drill two holes in either of the solid parts of the base piece, insert LEDs in the holes and wrap the wires to the LEDs. Draw designs on the outside of the plastic container that resemble coral, pour some substrate into the container and plant an aquatic plant in the substrate. Put a couple small fish in the tank, attach the base on top as a lid and plug in the power cord to turn on the lights.
Please don’t make this; this is way too small for a fish.
