On Friday I posted this puzzle.
I have just made this video containing 10 bets that you will almost win (kinda). About 1 min in I present one of my favourite puzzles – the vanishing square.
You can download your own version of the puzzle here.
So, the puzzle is….why does a square seem to vanish?
If you have not tried to solve it, have a go now. For everyone else the answer is after the break.
The following video explains the puzzle, albeit with a slightly different set of shapes. Basically, the top shape is not an exact triangle, and so when the pieces are rearranged, the area that makes up the ‘missing’ square are redistributed in a different way. Did you solve it?
I have produced an ebook containing 101 of the previous Friday Puzzles! It is called PUZZLED and is available for the Kindle (UK here and USA here) and on the iBookstore (UK here in the USA here). You can try 101 of the puzzles for free here.
