You have 3 empty containers: 15, 10 and 6 ounces.
You need to end up with 1 ounce of water in 2 of the containers.
Containers can be filled from your kitchen water tap!
How you do that?

If not familiar with water pouring puzzles, havva looksee:

1. Fill up the 6oz container from the tap.
2. Pour it into the 10oz container.
3. Fill up the 15oz container from the tap.
4. Pour from the 15oz container into the 10oz container until it is full. (That will leave 11oz in the 15oz container.)
5. Empty the full 10oz container down the sink. (I'm assuming there is a plughole near the kitchen water tap.)
6. Fill up the 10oz container from the 11oz left in the 15oz container.
7. There will be 1oz left in the 15oz container!! Da Dah!
EDIT: Oh no, that's not right. Just reread the question - you need 2 lots of 1oz. Woopsie!

Fill up both the 6oz and 10oz container.
Pour the water from the 10oz in to 15oz container.
Then pour 5oz from the 6oz container into the 15oz container filling it up.
This leaves 1oz in the 6oz container.
Good luck getting the 2nd 1oz container.

Good try Harry!

Try again!!

With my kitchen water? Fill up one of the containers and wait for the water to eat the bottom of the container. When the water gets down to the right level plug the hole.

That's 10 moves, not 9.
Here's what you did:
Code:
STEP   [15]  [10]   [6]
1     0      0     6 : fill [6]
2     0     10     6 : fill [10]
3    10      0     6 : dump [10] in [15]
4    15      0     1 : fill [15] from [6]
5    15     10     1 : fill [10]
6     0     10     1 : empty [15] : you don't show this step
7    10      0     1 : dump [10] in [15]
8    10      1     0 : dump [6] in [10]
9    10      1     6 : fill [6]
