Ok so you do it in these steps;

1. Take the 5 liter container and fill it up.
2. Empty the contents of the 5 liter container into the 3 liter container until it is full, leaving you with exactly 2 liters in the 5 liter container.
3. Empty the 3 liter container and transfer the 2 liters in the 5 liter container into the 3 liter container.
4. Fill up the 5 liter container and fill up the 3 liter container with the water from the 5 liter container until it is full
5. This leaves you with EXACTLY! 4 liters in the 5 liter container.

Here is the clip from the movie if you don't understand the above, also in the movie its done in gallons not liters.

Because you pour 1 liter from the 5 liter container into the 3 liter container because the 3 liter container still has 2 liters of water in from when you poured the 2 liters from the 5 liter container into the 3 liter one. :eusa_wall

Fill up the 5 litre jug, then fill up the 3 litre one with the 5 litre one, tip out the 3 litre one, put the 2 litres in the 5 litre into the 3 litre, fill up the 5 litre, fill the 3 litre up, taking away 1 litre from the 5 litre, leaving you with 4 litre in the 5 litre container.

put 3 litters in the 3 one and 1 in the 5?

although its probs already been done

>fill up the 5 liter container.
> use it to fill up the 3 liter container, leaveing 2 liters in the 5 liter container
> emply the 3 liter container
> pour the 2 liters in the 5 liter container in to the 3 liter one.
> fill up the 5 liter container.
> use it to fill up liter container, which will use 1 liter and the 3 liter container already had 2 in it.
> you now have 4 liters in the 5 liter container.

EASY PEESY LEMON SQUEEZY
fill the 5liter thing up to 4 litter line
DUH

Pur them both together, weigh them, divide the weight by two and keep pouring water into the other container until you have half the weight of the two combined.
