The answers I wanted were
1: Nothing to do with HV
2: I have only ever dropped a sliver of soap while showering and have it land on it's edge and stay there, twice in my life. It's probably one of those Schrodinger's cat quantum improbability things...

It's a tritium containing keyring. Glows for 10 years. It is radioactive with a count something like twice background if I recall. I've had enough kids, so I can use it as a keyring and keep it in my pocket rolleyes
Cost AUD$20 on eBay from the UK. Radioactive imports. Hmmmm..

Next is a very quick one. Which is the red laser?

I would assume it is the one on the right since the radation is pointing to the left...

Just to show that lightning strikes twice, even if it is on the opposite end of the world. I picked up some parts from my desk and this diode was left standing. I will never see anything like it happen again.

I would say the right laser since the hole on it is red, while the outside of the case is green.

..but I was naked. Were you confused

The lasers were obvious once you think about it but I almost labelled it wrongly. It is highlighting some aerogel but it wasn't up to scratch with clarity so wasn't used. Since everything was on my desk in front of me, I took a better shot.
The dirty hands are from taking apart a laser photocopier. After I finished and had discarded the junky bits, I thought "but where was the laser?"
