Well, the cool thing about a PV is that you CAN put it down or just stick it in your pocket and not worry about it catching something on fire or burning down & wasting away.
The vapor disappears so quickly, it's kind of hard to even get IN your eyes. However, the liquid itself DOES sting. My husband was popping the tip off a bottle and pulled too har and some splashed into his eye. It was quite red and it definitely stung for a while!
