Drinking Vision.
As i was pretentiously sipping on a glass of wine, trying to be pretentious i attempted to look through the bottom of my stemless wine glass. Then i thought, wouldn't it be good idea to have a glass or beer bottle that magnified or telescoped? Clearly my target market is the dude at the bar trying to A) magnify the view directly around him or B) get a better look across the way.
They already have bottles that tell you when they are cold, surely they'd try this.
