    Photo Diodes to Detect Laser Reflections

    Can anyone suggest a source for some photo-diodes that I can use to detect reflections from the cheap, toy laser pointer pens (650nm). I'd like to use these laser pens and photo-diodes for science fair projects for my grand kids. Any suggestions will be sincerely appreciated. LBC
