ok i just want to apologize for the text on my other trick color change.
step 1- you take four aces out of your deck.
step 2-next you put 3 cards on top of each ace.
step 3-after, you take 2 cards from the top of each pile and put them on the bottom.
step 4-after all that, you seperate the cards into 4 piles and then say,"all of the aces are going to appear in one pile."
step 5-flip over each pile slowly saying, " no aces" ect.
 
THE ACES SHOULD BE IN THE 2ND PILE THAT YOU LAYED DOWN.
YOU CAN PRACTICE THIS TRICK WITH THE ACES FACED UP FIRST.
