Simply breathe on the small glass disk and the word YES or NO appears!
If you are familiar with the Ghost Glass or Spirit Glass, you know that breathing on it, causes a word or symbol to appear on the otherwise clear glass disk. Well, this is an unusual version in that one side will produce the word YES and the other side will produce the word NO.
We supply you with the special glass disk and standard instructions but the actual routine is left up to you. Glass disk comes in a protective custom vinyl pouch.
NOTE: The image appears reversed so it must be viewed from the front; the audience will see the image correctly. This is done because you are producing words, not symbols.
