An impossible prediction effect!

The classic mentalism effect is now available as a video download!
A clear wine glass is seen on a table center stage, containing a black envelope with a prediction. The spectators are asked to concentrate on a single thought and to write it down on a card and seal it in an opaque envelope. At your command, they all throw their envelopes onto the stage. A random spectator selects any one of the envelopes (again: NO force!). Let"s assume the thought inside reads "ICE CREAM". She removes the prediction from the glass and opens it. She reads the prediction out loud: it matches the freely selected thought!

Now for the FINAL kicker: the lady is asked to open up the crumpled paper ball that was used to randomly select her as a volunteer. It reads: "Tonight, a beautiful lady called Annie will think of ICE CREAM!"

• The spectator is randomly selected
• No switch of the paper ball
• No stooges
• No secret assistants
• No pre-show
• No fumbling
• No sleeving
• No electronics
• They can really write down any thought
• The other envelopes all contain different words
• The spectator opens and reads the prediction herself
• Prediction and envelope, both are completely unprepared
