If you watch much local news, you see the results of them all the time.
It's a matter of context I guess.
I have observed something regarding my students and use of laboratory burners. I 've noticed that when I have shown them the result of hot metal or glass touching something flammable (I use paper), the incidence of minor burns has lessened.
Again, my intention wasn't to sicken or sensationalize, but to merely provide a context for the result of not being extra careful and redundant when doing this very dangerous thing we do. If I offended anyone, including you, I am sorry.
Well, since you put it that way, I forgive you.
