Passe Passe Dice

The magician displays a hat, and places a large, solid die into it. He then shows two rectangular tubes. He shows them empty by inserting his hand inside. He places the die into Tube #1. It's lifted up, and the die has vanished, only to be found inside Tube #2! The die vanishes from Tube #2 and reappears under Tube #1! This happens a few times until both tubes are lifted and the die is gone! Where is it? It is found to be inside the hat! Much fun throughout the magical routine.

Included:

Tubes and die.
