[chbot] Help finding a Youtube Video

[Mark Atherton]

Hey all, wonder if you could help me find a video on youtube.

Title is something like ‘home made magnetron (does not work)’

Produced by a lad in his late teens/twenties.

He is copying a design by glassslinger in a glass test-tube, but can’t 
make it work.

The video references yttrium oxide at some point; this is the chemistry 
I am interested in.

The local copy was accidentally deleted and can’t find it again.

Any help appreciated.

Thanks, Mark
