You don't need B at all.
Fill C from A leaving 4 liters in A.
Dump out the water in C.
Then fill C from A again, leaving 1 Liter in A

Depending on your interpretation, that could be seen as 3 pours: dumping the water from C requires pouring it out.

Wait a minute! Does that mean that if I use a siphon I can claim I did it with 0 pours?!?! I'm a genius!

I got it!

1. Continue pouring Bowl A into Bowl C until A is empty. C should now have 3 liters.
2. Pour Bowl C into Bowl B until Bowl B is full. Only 1 liter should be remaining in Bowl C after that.

okay here goes,
start by pouring the eight into the three, preferably overflowing 4 liters onto the floor because it's messy and the 8litre bowl would make a funny hat.
now pour the three into the five WITHOUT overflowing it.
that would leave you one perfectly measured litre in the 3litre bowl.

now parade around the room in your cool 8litre hat and enjoy a one litre drink!!!!!!!!!!!!!

Peace

This is a stupid puzzle and the posted solution is incorrect.

8 liter bowl is useless
5 liter bowl is useless

To measure EXACTLY 1 LITER:

1st pour: Pour out the 2 liter bowl
2st pour: Pour the 3 liter bowl into the empty two liter bowl, stop when two liter bowl is full, 1 LITER is remaining.

3-2=1 this is true last time i checked

that does not work since the bowls are not full ... for instance, there is no two liter bowl (the third bowl has 3 litres capacity and is filled with 2 litres)

oops misread the puzzle, solution is correct, but solution/ puzzle could be worded better - though subtle i think adds some clarity

Having three bowls each partially filled with water.
Bowl A (8 litres capacity) has 5 litres of water.
Bowl B (5 litres capacity) has 3 litres of water.
Bowl C (3 litres capacity) has 2 litres of water.

Can you measure exactly 1 litre, pouring only 2 times?

1st Pour: Using Bowl A, fill Bowl C (which contains 2L of 3L capacity).
2nd Pour: Using Bowl C (which now contains 3L), fill Bowl B (which contains 3L of 5L capacity)
The two liters from removed from Bowl C to fill Bowl B will leave exactly 1 Liter.

possible other solution though could be difficult: empty Bowl A, place finger along edge of the middle of the edge of bowl C and pour with one stream going into empty bowl and other in to bowl B. Should give 1 liter. also if emptying doesn't count as pour could empty both A and B and get two bowl each with 1 liter. Making to equal size & shape holes at bottom of bowl would also split water well

LOL, you guys are thinking to much. Just use a measuring cup. pouring half from one bowl, and the other half liter from another bowl. 2 pours. 1 liter.

You can't be sure how much 1 litre is. If you knew how much a litre couldn't you just empty one bowl and pour one litre out? Anyway, the solution i got is you pour 1 litre from A to C. Then, you pour 2 litres from C to B.

The question says "measure" 1 liter.

Although I believe the following to be correct:

A - B - C
is
5 - 3 - 2

Pour A(-1) in to C(+1)
4 - 3 - 3

Pour C(-2) in to B(+2)
4 - 5 - 1

Altenatively to "measure" 1 liter:

5 - 3 - 2

Pour B(-1) in to C(+1)
5 - 2 - 3

Pour B(-2) in to A(+2)
7 - 0 - 3

Since A is 8 liter, the remaining space should "measure" 1 liter.
