Another fooler from Germany.
I’d suggest extending the routine a bit by testing the spectator’s memory with the yellow die, covering it with the tube, turning it, and then asking if they know which number faces them when the tube is lifted. You could do this a few times and then end by asking them if they remember the color of the die!
There’s more to the props than you might imagine. Both the tube and dice are precision made.
The yellow die may be handed out for examination at the start. Also the tube is handled very freely and shown empty throughout, yet the “work” is activated with a simple press.
