Wine Drinkers Will Go Crazy for This Drip-Free Wine Bottle
For wine drinkers (both casual and the seriously invested), drips from bottles can ruin a nice shirt or tablecloth. There are several ways around these seemingly inevitable stains.

Use the fancy technique of wrapping a napkin around the bottleneck to catch drips. Drinkers can forgo the wine glass altogether and pour straight into their mouths. There's always the fancy twisting motion as you've completed the pour, but that gets difficult to perfect as you consume more wine. Wine connoisseur Daniel Perlman managed to use his physics degree to add yet another solution to this problem. He re-imagined the bottle spout to prevent dripping.
The biophysicist from Brandies University spent three years watching liquid leave the lip of bottles. He cut a groove just below the lip to ensure no drips.
Despite being a biophysicist by trade, Perlman has over 100 patents to his name. On his extensive list of accomplishments, a drip-proof bottle seems like the least noteworthy. However, Perlman noted it was one of his favorites. Wine lovers could already buy devices to reduce drips, but those required an additional purchase and had to be inserted into a bottleneck.
"I wanted to change the wine bottle itself," he said. "I didn't want there to be the additional cost or inconvenience of buying an accessory."
Thus, he decided to study the physics behind wines. He saw that drips happened most frequently when the bottle had been freshly opened and was full. Perlman also noted that wines curl back over the lip. This is due to the liquid's hydrophilic properties -- it attracts water.
Perlman and engineer Greg Widberg notched a groove around the neck of the bottle, situated just below the top. A rogue drop can't cross the groove and instead drops off the lip with the rest of the wine. For a single drop to make it across the groove, it needs enough force to go against gravity and jump from one side of the groove to the other. Perlman's groove, at 2 mm wide and 1 mm deep, is the perfect size to bar the wine droplets from crossing.
Perlman now has to convince manufacturers to change a bottle design that's a few hundred years old, and voila, millions of oenophiles will be saved of annoying drips. For now, fans might have to stick to drinking straight from the bottle to avoid pouring a glass.
