Drink it of course!

You excitingly take the vial and drink it down. You feel the cool liquid go down your throat and you get a cold chill rush through your body almost instantly. Looking down at your hand you see it slowly disappear.

All you see is the vial floating in mid air, and your shirt. You look at the rest of your body and anywhere your skin showed was nothing. Amazed at your own success you decide to go out and use this new power.

You decide to take off your clothes in order to be more inconspicuous. You look down and see nothing. Then walking over to the mirror you look and still see nothing. You are completely invisible, and the possibilities are now endless. You think of all the different things you could now. Yet where do you go first? Now to decide on where to go.
