Summary

What can a humble airplane sick bag teach us about physics, engineering, and the limits of the human stomach; And why are there people out there collecting thousands of them? Professor Hannah Fry and VSauce’s Michael Stevens turn an unlikely holiday prompt into a surprisingly rich exploration of flight. From the biology of motion sickness to the physics of turbulence, and from exploding crisp packets to next-generation aircraft design, they unpack how flying messes with your body and how science has made it (mostly) better. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit ⁠⁠https://cancerresearchuk.org/restisscience⁠⁠ Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).

Welcome to The Rest of Science. I'm Hannah Frye. And I'm Michael Stevens. I think we should probably

0:05.3

tell the listeners slash viewers, the origin of today's field notes episode, because I am currently on

0:13.6

holiday in Greece. And as we were discussing, what I could possibly do that was holiday related,

0:19.8

our producer suggested that we just grab something on the way.

0:25.5

And we do an episode on Sickbags.

0:27.3

At which point, Michael Stevens, would you like to tell the audience what you told us?

0:32.2

Well, yeah, I said, hey, I collect sick bags, barf bags from airplanes.

0:36.7

Because they change periodically. and it's history.

0:40.1

Someone needs to be documenting this.

0:42.4

And some of them are quite cute.

0:44.5

So my collection, some of it happens to be here.

0:47.7

So do you, do you collect them too?

0:51.3

Only the very plain white one that I picked off a B-A flight on the way here.

0:54.7

I can't say, I can't say, by the way, this makes you a baggist. Do you know this? This is an entire community of you guys. Well, yeah. I'm now joining you as a baggist with my, I mean, it's quite a pathetic entry being entirely plain white. Well, I don't have a British Airways bag in my

1:13.4

collection. Maybe when I come out to London, could you give me that one? Deal. How many do you

1:18.3

have in your collection, Michael? I honestly, I only probably have a couple dozen. It's, it's not very

1:23.4

impressive. There are people who are doing a much better job than me. There are. In fact,

1:27.0

there's a great rivalry at the very hearts of the bag is community. There are people who are doing a much better job than me. There are. In fact, there's a great rivalry at the very hearts of the bag is community.

1:31.3

There is the Ayrsicknessbags.com bag museum, which the owner of which says, I collect

1:37.3

bath bags. My collection currently contains 3,659 bags, most are from airlines. While this website and hobby is an enormous waste of time,

1:47.3

I like to think that it's a higher quality waste of time than many other places on the web.

1:52.2

And what better description of our own podcast, Michael?
