fill 7L from 10L and fill 3L from 7L

3L in 3L ___ 4L in 7L ___ 3L in 10L

empty 3L into 10L and refill 3L from 7L

3L in 3L ___ 1L in 7L ___ 6L in 10L

empty 3L into 10L, empty 7L into 3L, and refill 7L from 10L

1L in 3L ___ 7L in 7L __ 2L in 10L

fill 3L from 7L ___ this takes 2L, leaving 5L in 7L

empty 3L into 10L ___ this leaves 5L in 10L
