A jumbo Card (6 x 9 1/2) is shown to the audience. It has one spot on one side and four spots on the other side. It is shown again to have three spots on one side and six spots on the other.

The magician proceeds to explain to the audience how the trick is done and everyone understands. That is, until they find out that what the magician said is wrong.

But the real surprise is at the end, when eight spots are found on the reverse side. Spots seem to appear from thin air.
