Greg Wilson considers this a simple little effect, almost a throwaway. Nothing could be further from
the truth! You can do this stunning visual penetration on a moment's notice with a regular coffee
sleeve and drink stir, then hand out everything for examination with no gaffes, no palming, nothing.
If that's not the definition of a perfect effect, I don't know what is. Every magician should have
this effect in their arsenal. Thanks, Greg!
