Sabering champagne with a glass

You may know about "Sabotage" this famous technique for opening a champagne bottle with a saber, usually used for ceremonial occasions.

Well, this man is a pro for sabering Champagne but he does it... without saber. In fact he just sabers his champagne with a glass.

This is pretty impressive and it's a non dangerous way to saber Champagne. This should be called "glassering"!
