Fun with liquid nitrogen

[FramerDave]

Well, there's a mail on the ice cream guy's site allegedly from someone who worked at a Dippin Dots factory. He said they make them with N2.

Indeed they do. The ice cream mixture is pumped through a device that's sort of like a giant shower head above a huge vat of liquid nitrogen. As the drops fall in they freeze pretty much instantly and then sink to the bottom of the vat. From the bottom of the vat they are conveyed by screw auger to the packing station, and from there into a ginormous freezer at -50 degrees.

Thank you Modern Marvels.

Oh, and the very fast freezing means very very small ice crystals. The smaller the ice crystals, the creamier the texture for a given amount of fat. And as we've established adequately, it's a matter of personal taste.

Billy Connolly has a pretty good routine where he describes his teachers at school saying that he'll go nowhere. "You're a jellyfish, Connolly. A spineless jellyfish, and you'll never amount to anything!"

His response:

"Well, I'm ****ing rich."

As a teacher, I have to wonder where he went to school. Most teachers would be in some degree of trouble for saying that or similar to a student. I could see a coach in a playing situation saying it and getting away with it (or a teacher through the late 50s/very early 60s.

It was a private school in Belfast in the 1940s, I think. He is, like, old.

That, unfortunately, makes sense.
