Physicists calculate exactly how long that last drop takes

Patience is a virtue, depending on a liquid's internal friction. The rate of liquid draining depends a lot on its viscosity and internal friction. Breakthroughs, discoveries, and DIY tips sent six days a week. How much of your life is spent waiting for the last drops of syrup, olive oil, or even bodywash to drip from a container? This routine test of patience is owed entirely to complex fluid dynamics .
