There are 2 versions of Evolution you learn on the DVD. 1)The Impromptu version 2)The Gimmicked
Version. As for the Gimmicked Version I feel its been over thought and that a PK would be much
simpler. As for the "impromptu" version, it's actually pretty clever, you just have to be a little
careful not to move very quickly. This effect also can't be done with "ANY" bottle it has to be done
with dark bottles not clear or green bottles. All in all, it's a neat method and if you have the
spending money go for it!
