I’m the second one

I wonder how it works.
Which part of the blood is it reacting with?

Too bad the light is so dim. Seems to defeat the whole purpose of the concept somewhat.

I don't think they understand the concept. The blood does not provide energy for the light, it merely unlocks it

Second kind

So, someone uses glass plus chemicals to make a one-time use lamp that doesn't even give off much light, and the guy's purpose in inefficiently using these resources for such a flippant purpose is to,draw attention to how we mismanage our use of precious resources?
