Liquid Nitrogen Ice Cream...Enjoy!

Posted: Updated:


A unique treat is unveiled at the Tulsa State Fair.
Mike Kudirka of Nitro Ice Cream is using liquid nitrogen to freeze patrons' concoctions and turn them into ice cream.

The process was developed by chemical engineering students at Iowa State University.

The nitrogen is hooked up to the ice cream machine,  freezing the ice cream instantly - and it comes out at a temperature of about -40.

Kudirka says it's fool proof because the faster you freeze it, the creamier and denser it is - and who doesn't love that!
