This is genius. They should make nail polish that detects all sorts of shit.
Politicians in honkie-asia really need polonium detecting nail polish.
Women should have a cynaide nail too, to dip in the bastard's own drink after they detect rape drugs in their own, unless it's a stand your ground state in which case they should straight plug them in the middle of the bar and cite the nail polish color change as proof they were under attack by a rapist.
Didn't they have a straw that changed colors if it detected any benzodiazepine years ago? One of the worst things about banning smoking in bars is the increased potential of this occurring: folks put napkins or coasters over their drinks, assuming the bartender's looking closely or that they can trust their date/partner/stranger to not slip them a mickey. You're already letting your livers down, people. Breathe in the second hand smoke and reduce the chances of sexual assault.
Two funny jokes about this I made at work today: #1) [when told that a new nail polish could prevent date rape] "How, is it just so ugly that nobody wants you?" #2) "Here's my idea for a product: finger nail polish that has roofies in it! Then you just have to make the swap and she does the work for you!". Yes yes, inappropriate, rape culture, all that bad stuff. I can't justify it! I'm part of the problem!
