More solid brass chip magic from the Danish chip master himself: Per Clausen.
Effect: A white chip with a hole and two black solid chips are shown on both sides. With one of the black and the Holey white you do a lot of transpositions. You can use your hands or a special card. Or even the spectators hands. In a blitz the two chips change places. Can be repeated again and again.
Take the extra black chip and make a pile of chips with the holey chip on top. A shake with your hand, and the Holey chip is now in the middle. Once more, and the Holey chip is back on top. The Holey chip can even hop from top to bottom of the stack. Now give all three chips to the spectator. He will find, not one Holey Chip but TWO plus a black solid. Everything examinable.
