Funny enough, I still use the bunsen burner. I mostly do chemical reactions where you have to test and see the color of the flame. I get all sorts from mixing certain metals - blue, orange, yellow, red and green to help test different chemical compounds. It reminds me a bit of the current times with imugene though, but with the people on this forum. Blue (Sad), Orange (Confused), Yellow (Sheep), Red (Negative), Green (Postive).
I've got to say though, my favourite has to be the green.
