You brandish a large white card with a single enormous black dot on one side. Flip it over and voilà – four dots on the other side! Turn it again, and suddenly there are THREE dots! Flip once more, and look at that – SIX dots! You’ll regale your audience with the tale of how covering certain dots with your fingers alters their perception... They think they’re onto you until you flip the card one last time. And just like that, EIGHT dots appear! (Surprise!)
