I've wondered into the section of youtube where they're taping bananas. I need an adult

It's actually a Big Clive video on how you can test if something is a real UVC germicidal lamp by seeing if it'll "sunburn" a green banana:

He's been on a fake-UVC kick recently because it turns out aliexpress and ebay are now full of "UVC lights" that are not, at all, UVC.

(Ultraviolet light comes in three bands: A is mostly-safe blacklights, B is less safe but needed for vitamin D creation, and C damages DNA, so it can be used for sterilization)

UVC is fun because while it's good at killing off microorganisms, it'll also give you photokeratitis, which is kinda like a sunburn ON YOUR CORNEAS.
(This is why welders wear those big masks: arc welding puts off a lot of ultraviolet)

it apparently feels like your eyes are full of sand, and REALLY HURTS. Your eyes think it's a foreign object so your eyes water a lot, but it can't be washed out.

The treatment is basically "give painkillers and have them lie down in a dark room with a cool wet cloth on their eyes until the eyes heal on their own".
Fortunately the eyes heal pretty quickly, between 24 and 72 hours.

the really fun part is that the only real way to stop the pain is to use anaesthetic eye drops... but that's only really used when diagnosing the condition or checking for additional injury.

because they slow down the healing and also might hide any additional damage (since you can't feel it now) which could lead to permanent vision loss.

the moral of the story is DON'T SCREW AROUND WITH UVC unless you really know what you're doing.

fortunately (I guess?) most of the "UVC" stuff you find available for sale is totally fake.

real UVC is either special florescent tubes, or LEDs in special tin-can mounts (because UVC will destroy the PCBs!)

and it'll probably come with a timer system, because you want to set it up, hit GO, and then it'll give you 30 seconds to get out of the room and then turn itself off automatically after Xty minutes

There was a fun event back in 2017 when a promotional event in Hong Kong was decorated with UV florescent tubes (apparently accidentally) and it ended up giving sunburns and photokeratitis to a lot of the attendees. https://hongkongfp.com/2017/10/26/partygoers-left-burns-light-sensitivity-hypebeast-event-landmark/

and naturally I found out about this from... Big Clive! because he talked about UV lights back then:

The event was actually about the famous sexy-robot-artist
Hajime Sorayama, because Hypebeast was launching a line of clothing designed by him.

nothing more cyberpunk than going to a hongkong fashion show about robots and all the neon gives you sunburns on your eyes.

No wonder everyone wears mirrorshades.

also by "sexy robot artist" I mean he's an artist who draws sexy robots, not a sexy robot who is an artist.

or a sexy artist who draws robots, I guess?
