(Newser) – It may be a first-world problem—that little drip of wine that slides annoyingly down the neck of a bottle after it's been poured—but to one scientist, it was simply a physics challenge waiting to be overcome. Biophysicist Daniel Perlman at Brandeis University, an inventor with more than 100 patents under his probably well-designed belt, says he's solved the age-old problem by etching a small groove into the bottle itself, per Phys.org. (You can see a demonstration via this video.) To arrive at his solution, Perlman studied slow-mo videos of wine being poured, then calculated precisely how large of an edge would be required to catch the offending drip. The answer: 2mm wide, 1mm deep.

Gizmos already are on the market to stop the spills, while sommeliers might use a napkin to deftly wipe the bottle after a pour, but Perlman wanted to simplify things. "I wanted to change the wine bottle itself," thus avoiding the need for an accessory, he says. Bloggers sound intrigued. The drip issue is a "pretty obvious" flaw that has been allowed to linger for as long as wine bottles have been made, complains a post at BGR. Another at Food & Wine notes that an industry-wide fix would likely raise manufacturing costs. "But innovation has swept through the beverage industry before—remember when not all cans were wide-mouths?—so maybe a drip-free future is within our reach." (How does neon-blue wine sound?)
