This can be done in one pour if the bowls are symetrical.

- pour from the 8L bowl into the 5L bowl until the water reaches the top-edge of the bottom (very hard to explain, but try it in a glass or bowl to see). This will be exactly half of the volumn of the bowl and therefor = 4L.

i like your styles.

Pouring water II. - Back to the Water and Weighing Puzzles
Having three bowls: 8, 5 and 3 litres capacity. Share 8 litres in halves (4 + 4 litres) pouring water the minimum times.

Pouring Water II. - solution
1. pour 5 litres from the 8-litre to the 5-litre bowl,
2. pour 3 litres from the 5-litre to the 3-litre bowl,
3. pour these 3 litres back to the 8-litre bowl,
4. pour the remaining 2 litres from the 5-litre to the 3-litre bowl,
5. pour 5 litres from the 8-litre to the 5-litre bowl,
6. pour the missing 1 litre from the 5-litre to the 3-litre bowl (there should be 4 litres left in the 5-litre bowl),
7. pour the 3 litres back from the 3-litre to the 8-litre bowl (and that’s it – in 8-litre bowl 4 litres).

Wouldn't it be easier to fill the 5 liter bowl and pour the remaining 3 liters into the three liter bowl and fill the three liter bowl to the top from the five liter bowl?

That would be three steps.

This is the only solution possible..... otherwise you have to use another spare bowl.........

That's kool yaar........... From wr did u learn this method??????? It really works.....!!!!!!!!! Actually, it's when the water surface forms the diagonal dividing the space exactly into 2 halves....... It's really great.....

8 0 0 START
5 0 3 Pour 3 from 8 into 3
5 3 0 Pour 3 from 3 into 5
2 3 3 Pour 3 from 8 into 3
2 5 1 Pour 2 from 3 into 5
7 0 1 Pour 5 from 5 into 8
7 1 0 Pour 3 from 8 into 3
4 1 3 Pour 3 from 3 into 5
4 4 0 Pour 3 from 3 into 5

No dude, thats actually 7 steps u did, not 8. You repeated that last step for no apparent reason, your solution is as good as the first ones. It is different but same number of steps Nice job!
