NASA says Earth has about 370 quintillion gallons of water. https://x.com/NASAEarth/status/1638564098320510976?lang=en

USGS says One gallon = 15,140 drips https://water.usgs.gov/edu/activity-drip.html

370 quintillion * 15,140 = 5.6018e+24 seconds

= 9.3363333e+22 minutes

= 1.5560556e+21 Hours

= 6.4835648e+19 Days

= 1.7763191e+17 Years

Or about 177,000,000,000,000,000 Years?

The last stars will burn out in only 100,000,000,000,000 years, so no one will be able to watch this faucet drip the last drop.
