- Take pour as much water as you can into the 3 gallon bottle (which has 2 gallons in it) and fill it completely.
- After filling that 1 gallon left of space in the 3 gallon bottle, you should have exactly 4 gallons in your 5 gallon bottle

Your a genius. I kept watching that part over and over again earlier, even with the subtitles on, and I still didn't understand all of it. just everything after when the 3 gallon bottle has 2 gallons in it.
Did you understand it at the time, or work it out yourself afterwards?
