You're a genius if you can work out this glass brainteaser baffling most people An extraordinary difficult brainteaser has flummoxed many people who are asked to work out the answer to puzzle about glasses.
One person wrote on Reddit where the teaser appeared: "Start out with all the glasses in a freezer which is turned off so the contents are liquid.
But people must try and determine how the full and empty glasses can be made to alternate.
By moving only one glass how can you make them alternate between full and empty?".
This, however, must be done by shifting one glass which made the teaser hugely tricky.
