Physicist Develops Drip-free Wine Bottle


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. Over the course of three years, he has been studying the flow of liquid across the wine bottle's lip. It typically results in wine running down the neck of the bottle and dripping onto whatever is beneath.

There are ways to prevent spillage with nifty devices inserted into the bottle neck.

'I wanted to change the wine bottle itself, ' said Dr Perlman. Instead, the wine is forced to fall from the wine bottle into the glass below.

"I didn't want there to be the additional cost or inconvenience of buying an accessory".

For something that has just one job, you have to admit that there is a fairly fundamental design flaw in wine bottles.

Dr Perlman has 100 patents for everything from specialized lab equipment to, along with KC Hayes, professor emeritus of biology, a "healthy fats" in Smart Balance margarine.

Daniel Perlman, an inventor and biophysicist at Brandeis University has showed off a bottle with a groove cut into its lip. He noticed the problem was most pronounced when bottles were almost full.

Through extensive trial and error, Perlman finally settled on a groove design that measures 2 mm wide and 1 mm deep (0.08 and 0.04 in).

Now a wine droplet has the hard task of fighting the effects of gravity to make it past the groove.

Most recently, he made coffee flour, a food ingredient and nutritional supplement derived from par-baked coffee beans.

He is now in discussions with bottle manufacturers about adopting his design.
