A playing card is selected (2 of Hearts) and lost in the deck. The magician draws out a rectangular piece of clear glass from a pouch, cleans it with a soft cloth and places the same on top of the deck for a while.
Then he places the glass in front of his mouth and exhales a long breath on it. Oh! Presto! A miniature image of the selected card mysteriously appears on the glass for a moment and then disappears.
If desired the effect can be repeated again with a different card.
Exhaling on the ghost glass or putting it over a cup of hot water will bring same effect.
