Top Hat & Chip Mystery

As the magician pushes a little hat along the table with a magic wand eight poker chips appear in a neat row.
The four white chips are dropped into the hat followed by the four red chips. Both sides of the chips are shown.
With a wave of the wand, the chips reappear in an alternating color sequence.
The chips are dropped back into the hat in the same alternating color order.

The hat is once again pushed along the table and the chips magically change to their original order.
