Invented by Mike Thomspon, an English designer based in The Netherlands. The lamp contains luminol – the same chemical forensic scientists use to check for traces of blood at a crime scence. Luminol reacts with the iron in red blood cells and creates a bright blue glow.
To use the lamp, you first need to mix in an activating powder. Then, you break the glass, cut yourself, and drip blood into the opening.
You have to really decide when to use this lamp because it's only going to work once," Thompson said. "So it makes it kind of a poignant moment."
Thompson designed and produced the lamp in 2007.
