Donald Duck Teaches the Diamond System 🦆📐 Did you know Donald in Mathmagic Land (1959) gave one of the earliest lessons on the Diamond System? 🎱 In this clip, Donald uses basic subtraction to calculate a 3-rail kick shot. The formula is simple: Cue Position (3.5) - Natural Angle (2) = Aim Point (1.5). As the narrator says, "There is no guesswork to mathematics." Do you use the Diamond System in your game, or do you play by feel? Let us know in the comments! 👇 #Billiards #Snooker #Pool #Diamo
