Has anyone tried this? There is no demo video on the site.

I will start by saying I have not done THIS escape. I have done one like it, using a leather version of the Siberian Chain.

TO be honest, if it is what I think it is, I would say that this prop relies heavily on presentation. That is you could do this and look silly or worse look boring. Or you can come up with a good story and pater that turn it into gold.

I once saw Patrick Culliton perform a Siberian chain. He began with Houdini's lie that the escape requires a demonstration of brute force. He then did the escape, making it look (very well) like the lie was the truth and he powered out. We all know there was no power move, we all know how that is done, but Pat sold it so well as to make it believable and entertaining.

My thinking is that this will be the same. I can think of a few ways to sell getting your hands out. Your feet are another story. I hope there is a method beyond just sitting down and removing the strap.

Yep, according to the ad copy, it's a version of their "Old World Siberian," which I own. As such, I must assume that it is indeed what Cliff thinks it is.
