getting amount of 3 measured from 7 and 5 vials in mini-game

I can't figure out how to get to 3 measures in the mini game where you have two vials measuring 7 and 5 , and you need an amount of 3. I am going nuts with this. Anyone know how to get to level of 3 to pour into container?

Yes. First you mix the correct color, then pour it into the container 5. Then take container 5 and pour that into container 7. Then fill up container 5 AGAIN and AGAIN pour it into 7. The rest of what is left inside container 5 is 3. Hope this helps.
