The Magician Displays the 4 aces then places them back on top of the deck. He then shows the first black ace and places it on the table. Then he shows that there are 3 aces left. After doing so he shows the last black ace and places it on top of the other one. Now here is the fun part. The magician then takes the left over red aces in his hand and snaps them and when he turns them over he reveals that that he now has the black aces in his hand and the red ones are on the table! They have switched places!

This trick is suitable for all levels.
