Liquid Nitrogen Mystery!
Do you have what it takes to crack this cold case?
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: 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.
Think we're trying to pull a fast one with that jump cut? The full footage of the pipe cooling can be seen here.
