Drip-Free Wine Bottle
Wants!
There are several ways to prevent those inevitable wine bottle drips from staining your tablecloth. You can wrap the bottle in a napkin while you pour, just skip the wine glass altogether and drink straight from the bottle, or use your physics degrees to re-engineer the bottle’s spout so it never drips again.
As a wine aficionado, Brandeis University biophysicist Daniel Perlman has almost certainly tried all of the above, but he’s had the most success with that last approach. Over the course of three years, through some of the most enjoyable research he’s probably ever conducted, Perlman studied the flow of liquid as it leaves the lip of a wine bottle.
After a bit of trial and error, he found that using a diamond cutting tool to carve a two-millimeter-wide, one-millimeter deep groove just below the lip of a wine bottle was the simplest solution.
