These glasses will make your friends think twice before asking for a second drink (unless it happens to be the antidote).
Great for murder mystery nights, Princess Bride parties, and any day you want to give your friends a little scare.
“You Have Just Been Poisoned Etched Drinking Glass“, $15 at Geekatrix’s Etsy shop. (There are all kinds of other good geeky finds there–take a look!)
