Large size of Goshman’s Color Changing Ball to Square. Show a RED 2” sponge ball, push it into your hand, then remove it from the bottom of your fist BLACK. Kids think there is a red ball still in your hand. Open your hand to show a red SQUARE! David uses only the inside-out 6” red square, starting out as a ball and tossing it into the air to make it a 6” red square. Works easier when damp. See David’s routine in Kidshow Magic Kompendium. $15
