Blind-sight Outdone (with gimmicks) by Devin Knight - Trick Penetration Al James walks you throughNOTE: Do not confuse this with the original Blindsight. This 100% new method will fool those who have the original trick. The performer shows four manila envelopes. There is nothing written on the envelopes, nor are they secretly marked. He shows them freely on both sides and points out the envelopes are opaque. The performer hands the envelopes to a participant; saying inside each envelope is a different colored card: Green, red, blue, and yellow.
