Perform a pointless animal experiment by launching rats into the air. It's not cruel, they enjoy it really.
Slam the bottle with the hammer to project the rat into the air. Warning! The more power you put into slamming the bottle, the less you have to keep the rat flying.
Hold the left mouse button and drag the hammer to hit the bottle. Use the left mouse button to make the rat flap it\'s arms to keep it airborne.
