It is possible to measure 4 liters when you only have a 5 liter and a 3 liter containers . This principle also applies to measuring 4 gallons with a 5 gallon and 3 gallon containers. And measuring 4 ounces with a 5 ounce and 3 ounce bottle. Watch my video for all the details (by #HowToSolvePuzzles ).

I've used scale models of the 5 litre and 3 litre containers, so that the video runs for less time and it is easier to see what is happening. The same principle applies to measuring 4 gallons and 4 ounces, as these bottles are just scale models. This riddle has been made famous by the movie "Die Hard"
