This is a great effect. The method is incredibly simple. The presentation isn't complex. The gimmick
is absolutely tiny, so lighting, and angles aren't a problem at all. There is a slight set up and
clean up but until real anti-gravity is invented this is as simple and easy as it gets.
The
video is only 8 minutes long, it covers the basics but the method is so simple that it doesn't
really need much more explaination time than that.
