First, I admit I'm not a fan of the Oil and Water premise. There was always too much counting and
not enough motivation for the effect, for me.
David Regal's version WHOA! Get ready! The
backs are involved, too!
Four BLUE backed BLACK cards cleanly interlace with four RED
backed RED cards and SEPARATE. Twice.
Squeaky clean. It'll make you and your spectators
feel good all over!
The kicker ending has the separated backs instantly REMIX their colors
in the spectator's hands.
Highly recommended! Simple clean, beautiful!
