How to Stack poker chips with one hand

Take some ordinary poker chips and make two piles of four. Put three fingers on the side of one pile, and the thumb on the side of the other pile. Gently squeeze the chips together.

Put your fore finger in-between the two piles and run it upwards causing the chips to interlock one by one from alternate piles. Push them together into one big stack, and then separate them, ready to go again.
