To enhance the effect of the card guessing trick, you can use a special “magic” wire, which, when heated, instantly reveals the value and suit.
When performing a trick, you need to invite the spectator to choose a card from the deck so that he pulls out the one you need, corresponding to the properties of the magic wire. Then you, supposedly not knowing its value and color, lower the lump of wire into hot water or drink.
Due to heating, it will instantly unwind and bend to its original position. Do not straighten or twist the wire; when heated, it always forms the inscription “eight of diamonds.” You can also force it to take this form by heating it with a lighter.
