The video shows a nifty trick in which you can cut a chocolate bar into segments and then, when you place it back together, you are left with an extra square of chocolate.
People have been blown away by the Willy Wonka-inspired wizardry.
The video has had over 25 million views and has been shared more than 300,000 times. Some even hailed it as "witch craft".
But all is not as it seems.
The thing is, there is no way in hell you're getting unlimited chocolate by rearranging a few chopped up pieces.
The trick is simply a matter of geometry, whereby cutting something and rearranging its pieces makes up for the displacement of a portion.
Sorry folks but you're not getting unlimited chocolate any time soon. Unless, of course, you go and buy some.
