WARNING: Uncertainty! (both material & human)
Don't forget that you will be working with a highly inflammable material & think hard before you apply alcohol to other parts of your body such as, err...your nostrils; yes, it burns.
So, read all before you start. I take my paranoias seriously; you better do as well.
Many of you know that fax is a thermal paper, ie. heat sensitive on one side, but a few knows that it also gets drunk(!) ie. affected by alcohol. In this, my first, instructable we will deal only with the latter, Hyde'ing, side of fax. Dr. Jekyll also has boundless potential when you come to play with him. When you think of the ways thermal paper reacts to various sources & forms of heat you'd be amazed. (This will be another story, but you should start pondering on it. Let's see what we all come up with.)
Step 1: Ready, Steady
At least one roll of thermal(fax) paper
Alcohol (One I used is 80 proof lemon cologne, with a spray nozzle
A foam mat appr. a4 size (I used 1 cm. upholstery foam which is very handy for many things)
A fan of your choice (I used my hands)
