An intriguing effect with a carnival aesthetic.
Crystal Ball sees the truth and answers with ‘YES’ or ‘NO’.
A playing card is chosen from a regular deck. Next, you remove three other random cards.
The chosen card is mixed with the three random cards.
You introduce the crystal ball. Ask any question and you'll get a ‘Yes’ or ‘No’ answer.
To prove that the crystal ball works you show it each of the four cards.
Then one-by-one you place a card next to the crystal ball and ask "is this the spectator's card".
Against the odds, the crystal ball will only say “Yes” when presented with the chosen playing card.
