Blindsight

• Blindsight

Effect

Performer patters that Blindsight is the apparent ability to see colors and shapes which cannot be seen. You offer a simple experiment. You introduce 4 ungimmicked colored cards: Red, Blue, Green, and Yellow. These in turn are sealed into 4 opaque envelopes and mixed so that the spectator doesn't know which color is in which envelope. You ask him to point to any envelope. Free choice, no magician's force of any kind. You hold it up and ask him what color he thinks is inside. Assume he says Blue. You write "Blue" on the envelope. This is repeated 3 more times with the person freely pointing to any of the remaining envelopes. Each time he states the color he thinks is inside and the performer writes it on the envelope.

Performer fans the envelopes out allowing the person to see the names written on each envelope. Magician states he only needs three envelopes for the first part and for the person to remove one envelope and place it off to the side. Let's assume he discards the envelope with the word Yellow written on it.

The other three envelopes are opened one at a time, the spectator has correctly guess what colors were in each envelope. This is pretty amazing in itself but the kicker is still to come.
