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: Here's a puzzle we'd like you to work on.

Steve: A copper pipe is placed in a container of liquid nitrogen.

Joanna: The nitrogen boils rapidly, which is to be expected since the pipe was at room temperature to begin with.

Steve: The boiling slows as the pipe cools, which is also expected.

Joanna: But watch what happens next...

Steve: That's your puzzle. Why does the boiling suddenly increase right before the pipe finishes cooling?

Joanna: Give us your thoughts in the comments and we'll give you our explanation in a future video.

Thanks for watching! I hope you'll join us again soon for another experiment!

Steve: I'm pretty sure it's a guy named Eddie.

Joanna: Or elves. Could be house elves.

Steve: Could be.

Joanna: Umm-huh.

Joanna: Thanks for watching! And join us again soon for another experiment!

Steve: I hope you'll join us...

Joanna: How can I forget this?

Steve: This is like video 80 or something.

Joanna: I hope. You'll join us. Again. Soon. For another experiment.

It's just - it's been so long.
