I have seen part of this trick this done before, many years ago. Flipping a coin onto the fork arms is not new. However, I haven't seen the end of this before, but I question the practice of jerking the fork arms to re-position the coin in preparation for the drop into a bottle or container. Surely, this puts undue pressure and potential shock wear onto the valves, hoses, chains and cylinders that is detrimental to the machine.

Great for showing off and for showing great dexterity of control, but do we really want to encourage operators to do this as a matter of normality? All it really proves is that theinstructor is a show-off!
