The
Magic Marble Run
Illusion
of The Magic Marble Run
A silver marble is placed on the top chute. It rolls into the box and momentarily
disappears.
Suddenly, a blue marble comes out of the chute below, drops onto the next chute
and vanishes into the box.
Moments later, a red ball emerges and drops onto the chute below. Again it disappears
into the box.
Finally, the marble has changed back to being silver again as it rolls from
the last chute.
