- This Chamber is designed to simulate the vacuum of space! In this video I show the fabrication and some design aspects of the build.
In up coming videos I'll be testing the effects zero atmosphere has on house hold objects.
That's a great build! You should put a bar of ivory soap in there
Thanks Darren, interesting suggestion, will do👍
I've never seen anyone build something like this at home! We are curious what would happen if you put popcorn in there...
Thanks Norlan, awesome idea, I’ll test popcorn next video 👍
nice build!
What happened to the bloody orange!!!! I need to know.
Nothing yet, but I have concerns for the ongoing wellbeing of the Orange 😎
What sort of pump you using to evacuate the air
What's the thickness of the clear screen?
A follow-up video would be nice.
I am trying to build one to dry wood under vacuum.
Nice Idea, sounds like an awesome build. The screen is Perspex and is 15mm thick, but I have to say on full vacuum I can see the screen start to bow in. Probably 20 to 25mm would be safer. Hasn't broken yet having said that, Perspex is tuff stuff. A big factor would be the size of the window, smaller window is certainly stronger.
Just working on a new video for a different project now, but I'll try and do a follow-up video in the future :)
Subscribed. Do you know if a homemade vacuum chamber can achieve 1 mbar (0.75 torr, 0.75 mmhg)?
0.01 mbar?
Might that be possible in a rectangular chamber around 600 mm x 300 mm (24"x12")?
Hi Jonathon, thanks for subscribing. I think the level of vacuum depends on the pump you have. I was only able to draw it down to -13.5psi. Absolute vacuum is around -14.5psi. that last 1psi is difficult, my pump wasn't able to get it but if you invest $200 or so on a good pump I'm sure its possible (as long as there is not leaks in the chamber). Probably should note that if you make a 600x300 chamber make sure you use thick Perspex 25mm or if using steel10 - 12mm, as the pressure will want to crush it.
Thanks for the question Jonathon :)
Hi Thomas, Want to ask what thickness metal sheet did you take for the shell of the chamber?
Hi there, I used 3mm mild steel. This is quite thin so I added gussets either end as any flat surface with be a weak point and tend to buckle. If you are making plans to build a chamber I recommend over engineering it to be on the safe side.
@@thomaswompyward447 thanks for the information. I made a similar circular chamber of 400 mm I'D with 5 mm plates.
Moreover I have the ends dished torispherical. It's quite safe but it has become too heavy. So I was thinking of making a lighter one.
However your assertion has cleared my doubt and I think the 5 mm one is okay from buckling point of view.
Where do you get your vac pump?
Good old ebay🤘😊
Gloves, please
