Had too much to drink last night? Don’t blame yourself. Blame the wine glass.

"Researchers say people who hold the glass while they pour and those who pick white wine will drink more. Also, the wider the glass, the more you'll end up pouring." (Via Bay News 9)

The new study by researchers at Iowa State and Cornell Universities found simply holding your wine glass while you pour leads to a 12 percent larger pour. (Via The Daily Meal)
