"Why do research when I can just build it and see what happens"

I like that.... I like that very much...

[griffin]

12:07 That glass dome hanging almost half way off the table makes me nervous

[JustAnotherAccount]

This man is so smart that he can act dumb around electricity and still be safe

[shan_singh]

"why is it shocking me?"
*proceeds to touch it with bare hands*

[reemontel]

"it messes with my lights" - I love how calm he is about that

[jacq]

*Makes X-Ray tube*

*"Ahhh yes, the glow of death!"*

[z]

> *fires electron beam at very high voltage*
> Neighbor: Wow honey, that was some good tea, it made my chest tingle!

[PlasmaChannel]

“If your desk isn’t messy enough, then you must not be a maker” truer statements have never been said my friend. My apartment constantly looks like a giant nerd fight.

This was really cool mehdi!

[pmz]

12:07 I almost had a heart attack that glass globe has a death wish

[slovakiak]

One small piece of tungsten and he’ll start making x-rays. This man needs to be placed on a watchlist

[awgmax]

12:07 I'm certain he put that glass thing on the edge just to trigger us.

[redwolf]

Mehdi: *takes on the full power of a star*

Also Mehdi: "tis but a scratch"

[joelmuhizi]

Mehdi: prepares to turn on, power supply
My heart rate: 📈📈📈

[metalhat]

Nice work!
From the amount of Plasma I would expect a pressure of somewhere between 10 mbar and 0.1 mbar. For electronbeams that are used (either in Electron Microscopes (SEM/TEM) or for Electron Beam Epitaxy) in Lab settings we usually have vacuums around 10^-5 mbar, since in those the electrons flow much easier and are well behaved so that you can control and detect them accordingly.
For demonstration purposes a vacuum of ~10^-3 mbar should be enough, use some Argon to show the path of the electrons.
Also if you use a Helmholtz coil setup you can actzally adjust the path of the electrons into a circle and use that to correctly measure the charge of a single electron.

"I'm pretty sure at those voltages I would create some pulses of X-rays.... so lets not do it very long"

[infinityzer]

“Glass is uncomfortably close to falling off”

"why not just build and see what happens"
famous last words

[thedevilinthecircuit]

You can greatly improve the seal on your vacuum chamber by wiping a thin film of Vaseline around the lower rim of your clear container, laying a wet ring of RTV silicone on the base, and gently pressing the container into the goop. The Vaseline prevents the RTV from bonding to the glass. When the RTV cures (give it a full week), remove the container and wipe all the vaseline off both surfaces. You'll now have a custom-made airtight gasket.

[NikoBellic-hgun]

His last words is gonna be: "ok, lets plug it in".

This channel in a nutshell:
“Ow! What went wrong?!” *finds out what went wrong* “Wow, I’m such an idiot!”
Repeat for several episodes
