Magic Tricks

I was very happy to see a description that described the effect honestly... until I got to the line that said, "There's a completely free choice of envelopes AND lighters.". This is absolutely not true. One choice can be free, but certainly not both. The performer must ensure that the selections align properly. You can't possibly let both choices be completely free.

That said, this could be a fun effect. The idea of lighting a spectator's bill on fire creates some good tension. There is some handling you'll have to work on, but nothing especially difficult. I just wish the ad copy had resisted the urge to make the effect seem more miraculous than it really is.
