This is a great effect man! Although it is truly a bit boring at times, and you show your hands empty a few times too many, this trick is quite remarkable. I wouldn't call it a visual vanish though, because visual would be no hand-closing, just put it on your palm, 1,2,3 and it vanishes

You should try to market it, it definitely has potential.
Just a question is it hard to do? Like requires lots of practice, whether your hands are wet or dry, etc?
Keep up your good work mate,
