    I try to illustrate the safety concepts as I present them to the
    students, but too often, it seems like one unlikely safety rule after
    another. Does anyone do any demostrations of the safety rules?
    I use the "rocket exhaust" demo from the Tik Liem book to illustrate
    the "never look in or point a heated test tube" rule. I use a small
    squirt of water onto a paraffin fire to illustrate that there are
    different types of fires and that students should not try to extinguish
    one when they don't fully understand how to. I do the cow eye demo with
    an egg white and nitric acid. Are there any other demos worth showing
    students to make the safety litany seem more relevant?
