Frostbite Theater
Pewter Bells
At room temperature, pewter is a soft metal that is easily formed into new shapes. All of that changes once it's cooled with liquid nitrogen!
Announcer: Frostbite Theater presents... Cold Cuts! No baloney!
Joanna and Steve: Just science!
Joanna: Hi! I'm Joanna!
Steve: And I'm Steve!
This is a Jefferson cup made out of pewter. Pewter is a soft metal, so I can squish it into a new shape by squeezing it a little bit. And, since it's so soft, it makes a beautiful sounding bell.
Pewter Cup: Dink... Dink... Dink...
Joanna: Yeah, not really.
It doesn't ring very well because it's so soft. We can fix that, however, with... liquid nitrogen!
Now that it's frozen solid...
Pewter Cup: Ding! Ding!
Joanna: It rings a whole lot better!
Thanks for watching! I hope you'll join us again soon for another experiment!
Steve: Can I try it?
Joanna: Sure! Just be careful not to drop it. It's really brittle right now.
Steve: I'm not going to drop it...
Pewter Cup: Ding! Ding!
Steve: It really is nice!
Joanna: Um-hum!
Steve: Here you go!
Joanna: Aah! Steve! What did I just say?!
Steve: Oops...
