We exposed BEEF to the vacuum of space, then ate it!

Today we expose many different foods and materials to a vacuum chamber to simulate what they would experience in space.

You are a treasure. In the old world of the 90s you would have had your own Saturday morning science show. You're the PBS science guy for grown up millennials.

The food items may have tasted better if the weren't exposed to whatever came out of the phone, rubber bands and plywood glue. Next time I would suggest keeping food items separate from other materials.

Looking forward to more!

Great to see you back! You’re definitely one of the most underrated channels on YouTube

[ryanknight]

This is really some of the best science content I have ever watched in my life, I can think of no better science program being produced today that is as comprehensive while staying understandable and down to earth. I truly wish you had been my science teacher as a kid. stellar work, truly

You know what I really love about your videos?
It's about putting meat in a vacuum chamber, which could have been a 5 minute "LOOK AT IT"-video, but instead you give us almost ten times that, and explain the entire setup, even go into detail on how individual aspects of your setup function.

I never knew just how a diffusion pump works, I just knew *that* it works, and I thought that was enough... but watching your video, I discovered for the first time that diffusion pumps have that major advantage you mentioned, of not having any moving parts and thus not being very susceptible to degradation and failure.

Thanks for always taking the time to do the science and engineering justice, instead of only providing bite-sized "highlights".

Thank you! You and the team are unbelievably dedicated to thoroughly testing and researching every topic. I'm a 41 yr old science hobbyist that enjoys the level of detail and wisdom you painstakingly include in every recorded experiment.
Keep it up!!

I love how we always get detailed instructions to play along at home. Like we’re all building vacuum chambers and modifying lightbulbs.

[clownhands]

Just wanna say I appreciate the extremely long takes which are a signature of your channel. Talking precisely for this long is hard. Mad respect!

[groundcontrol]

The chickens keeping you company were one of the best parts. You're definitely living life to the fullest. Cheers for nearing a million subs, a metric which pales in comparison to, and isn't representative of the amount of deep knowledge that's shared & well presented across such a diverse range of topics in the library of this channel. I hope many people are keeping archives of these videos so they'll never be lost to time.

Your channel: one of the rare few that gets a watch regardless of video Title, Thumbnail or Topic because I know it's going to be quality and interesting. Thank you for great content.

"No, it was not a tax-deductible trip."

I would love to have you as my professor for just about anything. I have learned so much from watching your experiments, the way you show and explain how things work in the process is brilliant.
I am learning so much. I don't know entirely when I will be able to *use* that knowledge, but it will come to me when I need it most.
Thank you.

I watch some of these videos as it is somewhat a pleasure to watch someone so methodical and thorough. Thank you for such informative and entertaining videos.👌

[Messier_M]

This channel is gold! 👍 You’re an amazing teacher. This has become my favorite channel. Keep up the great work! You’re so close to a million subscribers. 👌🏻

"if you're wondering, yes, i have diffusion pumps laying around - but i also have *points* turbomolecular pumps... just laying around"

what an absolute legend

[sophiophile]

Love this. I also hate that feeling when someone asks 'but what are you gonna do with it?'. But that's how I went from high frequency vacuum tube plasma flame, to a plasma tweeter!

Unless you have a dust removal system I'm unaware of, I'm surprised you are dry cutting glass with no protection for your lungs other than the face shield. Doing stuff like that a couple times irritated my lungs worse than smoking for a decade.

I also really recommend getting a foredom hanging motor instead of a dremel. More power, no gyro motion when the speed changes, handpieces that can produce reciprocal instead of rotational motion for 'engraving', etc.

[drfirechief]

This was one of the most entertaining as well as always informative shows I've watched so far. The contrast between the technical, safety and engineering aspects against the letting the balloon fly, eating the beef and pork was absolutely epic. Thank you for all of it!

[copypolice]

Love your videos. How about trying cold/contact welding?

"Cold welding is the best process to use when fusing metal in such a volatile environment. It dates back to the 1940s and is considered a general materials phenomenon. In a vacuum such as space, two similar materials like metal fuse together through contact welding."

[tolisl]

This is definitely the most pleasant channel to follow. I love everything about it. The topics, the presentation, everything. Please keep up. Thank you very much

[mattp]

Another fantastic video! I love that when you go off on a tangent, that becomes as educational as the main topic. You are the single best science teacher on YT! Full stop. Can’t wait to see you get to 1, 000, 000 subscribers.

"That maybe too sensitive for example we've held on to a couple of videos on advancements in crisper technology because of the recent global human malware event over the last couple of years". Brilliantly put in words.
