NEW STEALTH GIMMICK!!!

Two bottles of Coke and two tubes, a spectator uses one set and the performer uses the other.

Both covers are shown empty and then placed over the bottles.

They are inverted back and forth, the spectator following every move.

HOWEVER, when the covers are raised, the performer's bottle is always UPRIGHT.

The spectator's is always UPSIDE DOWN!!

As a climax, show that your bottle has turned into a bottle of Diet Coke

IMPROVEMENT OVER YOUR AVERAGE TRICKY BOTTLE!!!
