The magician displays a packet of regular-sized cards featuring the Ace of Spades, King of Spades, Queen of Spades, Jack of Spades, and Ten of Spades, respectively in a row.
He says, "These cards are magic cards; let me show you one of their magical powers."
The magician whispers something to the cards, and suddenly, the cards change in size: the Ace of Spades becomes giant-sized, and the other cards progressively shrink right in front of the audience.
Final card measurements:
Giant Ace of Spades: 18 x 11 cm
King of Spades: 11 x 8 cm
Queen of Spades: 9 x 6 cm
Jack of Spades: 6 x 4.5 cm
