Just press play. Press Undo if you want to see it a second time. Works good on my PC, but you may have to reposition the beer bottle or the release box above the slinger in order for it to work.

Rev A: Added beer to bottle.
Rev B: Sling now moves freely and is not controlled by string to hand hinge angle.
Rev C: The first string rotation is in front of the man and the second rotation is now in the back. This is how it works in real life.
