Happy Filled Glass

Draw a path so the water can flow into the glass and fill it up making it very happy. Fill it up to the dotted line and use as little ink as possible to get 3 stars on each level.

Drag across the screen to draw. Use as little ink as possible to get 3 stars on each level. The indicator at the top shows ink usage levels needed for each star. Note that you can draw more than one line segment by releasing your finger/mouse button and starting a new line elsewhere.
