GREAT AND UNDERESTIMATED PIECE OF MAGIC.

Great performance, it's a good trick, but mine just doesn't work smooth like yours it seems ... . I've got three of them and not one works Perhaps I'm doing something wrong ... .

I understand you perfectly, this is my second Wonder Window, I got it just last week...the first one just didn't work smooth as you mentioned...the one of the video works very well and that was the reason I decided to made the video...this is a trick that when the mecanics works well is a pleasure to perform and because of the proportions of the props is very deceptive...and the best of all, it can be examined before and after.

Here you can see a video demo of The Frame of Destruction:

Phantom House is also examinable. I bought it back in 1996 and once has thought of throwing it away. Only until recently I realised it's a Tenyo product.....Silly me!!!
