Ball and Tube......$1.50
This is the classic pocket mystery where a solid steel ball bearing
slowly and mysteriously sinks down inside a metal tube that is
smaller in diameter than that of the ball. Then the ball rises back
from the interior of the tube and comes to rest on the tube's top
edge. Everything is passed for examination and no one else is able
to accomplish the effect.
