I totally agree that this method is valid:

Fill the 3, pour it into the 5. Then fill the 3 again, pour into the 5 until the 5 is full. Now you have 1. Empty the 5 and pour the 1 into the 5. Fill the 3, pour it into the 5. Totally works. So does the way indicated at the beginning though.

I don't know about this half filling thing, you'd have to be really good at eying "half" and I think the other couple ways are more exact.

fill the 3 litre. pour it into the 5 litre. fill the 3 litre again and pour it into the 5 litre until it's filled. there's 1 litre exactly left in the 3 litre. empty the 5 litre, pour the 1 remaining litre into it from the 3 litre. refill the 3 litre and pour it into the 5 litre bowl. there is now 4 litre exactly in the 5 litre bowl

Actually to do justice to loserfreak his explanation was indeed correct.... look
you fill the 3 then pour it into the 5 , you now have 0 in the 3 and 3 in the five then you fill the three again, pouring it into the 5, since you cannot obviously overspill water making the problem unfair you cannot put the entire three into the five for that would make it 6 in the 5. So to correspond to this you now have a full 5 and 1 left over in the 3. Empty the 5 and pour the 1 left over liter into it.
You Now have 0 in the 3 and 1 in the five. refill the 3 and pour it into the 5 leaving you 0 in the 3 and 4 in the 5.

Here's what I'm thinking:

1. Fill 3 liter with water, pour into 5 liter (now 5 liter has 3 liters of water)
2. Fill 3 liter with water again, pour into 5 liter until it's full the 5 liter is full.
3. You should have exactly 1 liter in the 3 liter bowl.
4. Dump the water out of the 5 liter bowl.
5. Pour the remaining 1 liter into the 5 liter bowl.
6. Finally, fill the 3 liter bowl with water and pour it into the 5 liter bowl, voilla exactly 4 liters in the 5 liter bowl!
