When I first heard about this video, before watching it, I had a slight moment where I thought that maybe somebody had come up with a great new way to peel apples!
Boy was I wrong, this looks about as dangerous and inefficient as possible, at least in terms of ways to peel an apple. I can think of many things that could go wrong in this scenario.
However, it is one of those situations where you just have to try it, or watch somebody try it, to find out if this is the best way to peel apples or not. In this case, I would say stick to conventional methods.
