The magician tells the audience that he was visiting a volcano's crater recently, when something unexpected happened to one of the props he had with him (because no great magician leaves home without his cards, dice, coins, etc.).
When he reached the top of the volcano the die fell out of his pocket and into the crater. It completely disappeared!
As he tells this story, he removes a jumbo die from a shiny cube and puts it on the table.
The jumbo size of the cube and the die makes the audience chuckle. Only a magician would have a jumbo cube and die in his pocket?
"Oh my God! My favorite die!
But a miracle happened!
The volcano gave my die back! But in several pieces!"
A snap with the fingers and while lifting the silver cube, several small dice tumble onto the table in place of the jumbo die!
The magician tosses the shiny cube in the air, showing it completely empty!
Combining the trick with the Jumbo Joker Die:
The magician shows the audience an empty tube and a jumbo die.
He tells the audience that the die can be placed into the tube from below or from above, but these would be too easy for a magician.
He places the tube on the middle of the table.
He takes the die under the table and then magically pushes it through the table, into the tube!
After the knock, he lifts the tube and there is the die!
Then he covers the jumbo die with a silvery cube.
A snap with the fingers, and when lifting the silvery cube several small die spread onto the table instead of the jumbo die!
He throws the silver cube in the air, it's perfectly empty!
