This is one of the best ideas I've seen yet. Simple, but awesome. Unfortunately, I could not prevent sideways momentum from ruining any chance at flipping the bottle. The actual flipping mechanics were so close to feeling good, but I could not flip straight enough to get any control over them.
I did, however, score quite highly. You can flip off the bottle as many times per throw as you want, so I just did that until I got a good flip randomly. Not satisfying. But seriously, a little fine tuning and this could be excellent. You could make more physics objects to flip, fine tune the flipping so I don't have the problem above, limit flip offs to 1 per throw, and this could be a great time spender.
