The magician has five elegant acrylic cards, each with a different figure between 1 and 10 on each side. The figures change depending on the visible side, which allows a multitude of possible combinations. The cards, red on one side and yellow on the other, are given to the spectator who inserts them freely into a special medium while the magician turns away. Once all the cards are placed, the numbers are completely hidden. However, without asking any questions and never looking at the cards, the magician turns around and instantly announces the exact sum of the figures chosen! The public can even check the result with a calculator: the amount is always correct! A quick, visual and amazing effect. Perfect for living room or stage magic.
