Yeah, I saw a magic trick where the magician shows a small round black case. Inside are 3 blackish discs. One disc is all black. Another has a sun on either side. The last disc has a sun on one side but not on the other. I asked him what trick it was and how to perform it, but he didnít teach me. Can anyone tell me what magic trick that was and how it's performed? Thank you very much in advance.
