Present your normal bicycle game to your viewers... front and back
As well as your four predicitions without revealing the message.
Without any suspicious gesture share the game in two and place the packages on the carpet.
From there, these are the spectators who manipulate the game.
Ask the first Viewer to take a small deck of cards of the first heap, it will return it and rest on the second. (he takes freely the number of cards he wishes to...)
Now ask the second Viewer to take a small package of second heap, and will return it and rest on the first. (idem... the quantity of cards is totally free...)
Your viewers will continue as many times as they want... no problem
When they decide to stop, take these two packages to not to make one.
Do read the first predicition... She'll tell you: "You have in your game 19 cards face down"
The viewer can only confirm your prediction... whereas you have never touched the game for reversals.
The second will tell you: "these 19 cards remove the 8 red cards"
Once again, your predicition is excellent... Applause
The third will tell you: "there's only the odd black...!
After verification, the spectators are a 4 clover... that does not match your prediction?
A moment of silence! ... your viewers rub already hands... the magician was wrong!
Not for long, ask them to return the fourth prediction
Surprise! the card is 4 clover...
Excellent tour with twists and turns
These are your viewers who use the card game, I repeat... Normal... let him review...
Fully automatic lathe!
