  • I have not tried this myself, although I have heard
    good success with it: Glo Germ. It is a harmless
    fluorescent colorless substance you can plant
    somewhere in the room, and after the end of the class,
    you can show them the importance of washing their
    hands after every lab by shining a black light on
    them. I believe Flinn sells this stuff, but I don't
    know if there is anything else available in a
    traditional stockroom that would work just as well.
    Good luck.
