Aquarium Algae Scrapper

i designed this so i could have an aquarium algae scrapper that was much more powerful then store bought scrapers. just put a dab of super glue on one end of the 1/2 inch x 1/2 inch rare earth magnets. and firmly press them in to their hole as it is a press fit though the magnets will slip out with out glue. just make sure to glue them in so attracting poles are facing the other piece.
