anyone know the answer to this-
place 6 water glasses in a row. the first 3 glasses should be filled with water, the second 3 empty. you must rearrange the glasses in the row so that they are alternately one filled, one empty, one filled, one empty, and so on. this must be done by only touching 1 glass. can you explain how to do this.
i already know the answer IS NOT- move the other glasses using the one glass you are holding.
