Silver Ball Mystery (2152)

Show a small box. Open it and remove two red dice, two metal rings and a steel ball. The box is now empty. Totally.

Close the box and hand it to the spectator for safe keeping.

Form one large tube with the two small rings. Place the steel ball on top of one of the dice, then set the tube over die and steel ball. Place the second die into the tube.
In a blink, the steel ball vanishes! They can examine everything! The ball is really gone!
The spectator opens the box they are holding and inside is the missing ball!

Great close-up magic.
