This looks like real magic trick when someone cracks an apple with their bear hands. It's very simple to use and anyone can do it.
You can do it to impress your friends, or some hot girl you wanted to date.
First Step : Grab an apple and insert your base of the thumbs into the stem area ( Make sure the stem is taken out )
Second Step : Grip hard and roll in opposite directions
There will be more easy tricks that you can do at home tomorrow. Time to impress people or win some bets.
