No matter how much of a wine aficionado you are, you can't escape the pesky wine drip on your own...unless you're a biophysicist.
If you're a wino, you more than likely have noticed how easy inevitable it is to spill a stream of wine down the side of the bottle after pouring. Sommeliers are aware of this issue and wrap a napkin around the neck, but Brandeis University biophysicist Dan Perlman has gone a step farther and invented a drip-free wine bottle.
Any liquid poured from a glass bottle tends to curl back and run down the side of the bottle because glass is hydrophilic (attracts water-based liquids). Though a particularly dedicated wine drinker can attach various contraptions to the bottle to avoid the dreaded drip, Perlman was inspired by his background to nix the problem at its source by using a diamond-cutting tool to cut a groove below the lip of the wine bottle.
"I wanted to change the wine bottle itself," he said, according to the university's site. "I didn't want there to be the additional cost or inconvenience of buying an accessory."
Reads the university's site:
A droplet of wine that would otherwise run down the side of the bottle encounters the groove, but can't traverse it. Instead, it immediately falls off the bottle into the glass along with the rest of the wine...For a drop of wine to make it across Perlman's groove, it would have to travel up inside the groove against the force of gravity or have enough momentum to jump from one side of the groove to the other."
Science: It helps get you drunk.
