I snitched this optical illusion off of G. Sarcone’s website, and would like to ask you a simple question: which of the two choppers has a longer line painted on-top of it? Are they the same? Is the red line longer? What do you think? I can assure you the answer will shock you. That’s it for now! No need to ruin this great optical illusion with some unrelated chit-chat. For more similar ones, check relative sizes cat.
