3 pieces are arranged next to each other. Can you determine which one is larger?
It’s a mind blowing illusion because although the pieces appear to be quite differently sized, they are actually all the same! Whichever of the pieces is on the right will appear largest. The piece on the left will appear smallest.
You can probably envision the fun you might have messing with your friends and family with this oneJ
This model has a fiddling mouse, dancing ducks and a dancing pigs lasered on the pieces.
