Scientist claims to have created drip-free wine bottle
Daniel Perlman, a biophysicist and inventor from Brandeis University, has claimed a new wine bottle created by him is drip-free. Perlman added a two-millimetre groove to the tip of the bottle that helps to catch the liquid as the bottle is tilted back after pouring the wine. Perlman studied slow motion videos of wine being poured for three years.
