After a recent event in Hong Kong where people attending a fashion event were exposed to dangerous levels of short wave ultra violet energy, I decided to make a video on the different types of UV tubes available on eBay. That includes the dangerous UV-C type that can cause eye and skin damage.

One thing I missed in the video was the importance of UV in the making of vitamin D in your body. A reasonable amount of exposure to sunlight is actually desirable.

It's been pointed out that the main mercury hazard to hatters was the use of mercuric nitrate in a process called carroting.

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
