Monecula is a fun game where you'll get to learn chemical compositions for common items while working on the physics of building. Your job is to get the molecules into the flask. If the molecule gets moving and does not make it into the flask you have to start the level over so only click on those when you think you've built a good path to the flask. Use the mouse to click and drag on movable objects to make a way for the molecules to get safely into the flask. There's a lot of strategy and fun in this game so give Monecula a try and good luck!
