Brandeis Physicist Invents Drip-Free Wine Bottle

WALTHAM, MA – Who knew physics could be so fun? Brandeis biophysicist and wine aficionado (we're assuming) Daniel Perlman applied his expertise to the source of every wine drinker's frustration – the drops, or if you're especially unlucky, the steady stream that runs down the side of the bottle while pouring.

For three years, Perlman studied the flow of liquid across the lip of a wine bottle in the hopes of saving tablecloths the world over. He cut a groove just below the lip of the bottle, and the drip-free bottle was born.

Perlman found that spillage was most extreme when the bottle was full or close to it, when wine curls backward over the lip and down the side. The 2-by-1 mm groove prevents the stream from passing and redirects it into the glass.

This isn't a one-off for Perlman, either. The biophysicist has more than 100 patents to his name, ranging from lab equipment to a home gas detector. But ending 200 years of wine bottle designs might be his most ambitious project yet – according to the school, Perlman is currently in talks with bottle manufacturers about adopting his design.
