    A biophysicist from Brandeis University has created a drip-free wine bottle that promises to keep even the most crisp tablecloth stain free.

    Many have fallen victim to the wine stain on the table cloth from a rogue droplet that rolled down the side of the bottle. Or the little drop that plummets from the bottle neck as you move the bottle away from the glass.

    Daniel Perlman, the biophysicist behind the drip-free wine bottle, spent three years studying the flow of wine over the lip of a wine bottle. In the end he solved the problem by cutting two millimetre groove in the bottle just below the lip.

    I wanted to change the wine bottle itself,” Perlman told a writer for the university’s website in an interview. “I didn’t want there to be the additional cost or inconvenience of buying an accessory.”
