I know this will seem stupidly simple once someone explains, but my brain has been struggling for a minute and I was obviously impressed by this because it’s a screenshot of an advert that’s been sitting on my phone since forever.

    • Fill 5l
    • Use 5l to fill 3l
    • Ditch 3l
    • Your 5l now contains 2l
    • Move 2l from 5l to 3l
    • You now have 0l and 2l
    • Fill 5l again full and fill 3l to the top Now you have 4l in 5l and 3l in 3l

    Overall whoever sets this task should be shot as you just wasted a crap ton of water instead of using a measuring jug…
