Roller Coaster is a close-up magic trick that uses an optical illusion disguised as a drink coaster made out of slate. A spectator chooses a card, and the magician claims to make it appear underneath their cup. After building anticipation, the card doesn't materialize as expected. Instead, when the cup is lifted, the coaster's scratch marks reveal the spectator's chosen card when viewed from a certain angle.
