You show, one by one, red and black cards perfectly mixed. That is, you show a red card, then a black card, then a red card, a black card, and so on, until you have shown 8 cards. But when you are done with showing the interleaved cards they are already separated.
This count is perfect for an oil and water routine or any other situation where you need to show cards mixed, but in the process of showing them mixed, they are being separated.
