Champagn disgorging

[chappers]

Hi, I want to freeze the neck of my champagne bottles for disgorging. Has anyone ever tried using this before? I am using glass bottles and hollow plastic champagne stoppers.

Concentrating a stream of coolant on a small area of glass seems like a good way to shatter it.

Dry ice in a salt water solution.
