to play: FILL: drag container to under water stream EMPTY: drag container to far left POUR: hold one above the other and press space move the containers and change the amount of water in them. the goal is to make the largest bottle have 6 Liters. the two bottles can hold 7 & 5 Liters max.
the only real change was the addition of the graph above. I was inspired to do this by http://www.cut-the-knot.org/wgraph.shtml credit for original game goes to The-Whiz
