First things first. . . relying on video is the best way to not learn things. While it can be a great asset in your learning to be overly dependent on it will cause your magic to "fail" when it comes to novelty and being able to put a personal "signature" to things.
In regards to this particular effect there is one video based on a slightly different method that Banachek does recognize Lior Manor's "
Invisible Touch" which is actually "cleaner" than the versions offered by Banachek, McCleod, and Karmalovich even though it does require a simple gimmick (that's very easily hidden or ditched without notice.)
DO NOT go looking for the McCleod or Karmalovich methods in that both were kept on a very short (by invitation) release and are not available LEGALLY.
I should point out that there is a very expensive folding chair made in Israel that will give you a similar effect and too, Taylor Imagineering has the Wraith (the most advance version of Real Ghost) device which may prove a tool of interest when it comes to embellishing the original effect, delivering a real time tap. I dare not say more on that front . . .
