Frostbite Theater

Announcer: Frostbite Theater presents... Cold Cuts! No baloney!

Joanna and Steve: Just science!

Joanna: Hi! I'm Joanna!

Steve: And I'm Steve!

Joanna: Today, we're going to be making liquid nitrogen ice cream!

Steve: Now, if you've seen our channel before, you might realize that we've done this before.

And, we have!

Liquid nitrogen ice cream was the very first video that was intentionally made to be put up on YouTube [by Jefferson Lab]. But that was sixteen year ago!

Joanna: Whaaa!

Steve: Hopefully, the thought is, we've gotten better at this.

Joanna: Maybe.

Steve: Maybe. We'll find out.

But ours is a very simple recipe.

Joanna: First, you take two quarts of half and half.

Steve: You have one cup of sugar.

Joanna: And four teaspoons of vanilla.

Steve: So what we basically have now is melted vanilla ice cream.

The key, though - Cooling this off, right? The secret ingredient to liquid nitrogen ice cream is the liquid nitrogen. And, happily, here at Jefferson Lab, liquid nitrogen is not a problem.

Again, if you've been on the channel before, you've seen us liberally spill this around.

Nitrogen, the main component of the air. And, in its liquid state, currently, right now, it's boiling. Three hundred twenty one degrees below zero. All this nice foggy stuff... is just fog.

Right? It's water vapor from the air that we're cooling down -

We cool the air below the dew point, the water condenses out, and you get clouds!

And once we have our ice cream nice and mixed we're going to start adding in the nitrogen to cool it off.

Now, this process does take a few minutes. It's going to be like three or four minutes of us... Mixing [stirring] and adding and stirring. Not the most exciting video. We're going to fast forward through this. If you really want to see the entire thing the full video will be linked in the description below. And you can watch four minutes of mixing and stirring the ice cream. So, if you're going to fast forward, we'll see you on the other side.

Otherwise...

Steve: Alrightie!

So, if you didn't stick around with us, we're back! Ice cream is now made. Add toppings as you like.

Joanna: Or mix ins.

Steve: And enjoy your nice, frosty treat!

Joanna: That's right! Thank you so much for watching!

Both: Bye!

Steve: That's a wrap!

Joanna: It is!

Steve: Did I get ice cream on my back?

Joanna: Probably! I held it away! You did not! Yay!

Both: And thus ends Frostbite Theater. Thanks for watching!
