DIY Magnet Aquarium Cleaner

Keep your hands dry while you scrub your aquarium! Place a plastic bottle cap on a stamp pad and stamp the rim of the cap onto a piece of polystyrene. Cut out two circles from the foam, place a dot of hot glue on one foam circle and press a magnet into the foam. Cut three circles of felt, set the polystyrene circles on a felt circle with the magnet facing the fabric, wrap the felt over the foam and push the bundle into the bottle cap. Set a magnet between the remaining two pieces of felt and hot glue the edges of the circles shut. Drop the fabric circle into your aquarium near one side of the glass, use the bottle cap magnet to hold the circle against the tank and move the magnet to scrub the walls of the aquarium.
