Spin the bottle help

Hello,
I am making a spin the bottle game. I can't figure out how to make the bottle's spin speed controlled by how fast you swipe your finger. I want it to work like the wheel of fortune, the faster you swipe the faster it spins.
Thanks!

If I had to guess, you'll need an actor to track the finger's movement from point A to point B, and then use that as a factor in the rotational velocity.
I would also look at the Throwing Objects video. I know you're not throwing objects, but this one has some application to what you're trying to accomplish.
Incase anybody was wondering, here is how I ended up doing it:
I put a ball at the end of the bottle that had TB's throw technique on it. I then took the linear velocity(X,Y) from the ball and set that as rotation speed of the bottle. So the harder you flick/swipe the bottle the faster it will spin.
