The species needs a lot of drainage so I added sand and started to mix it in the dirt with my hands. Light was fading fast in the sunset. To my surprise some short cylinders started glowing from nowhere. It was poisonous green; kryptonite green. Little 2-3cm bars glowing on the kind of fluorescent green that everybody associates with the word radioactive; all around the pot and too close to my fingers. Yuck! I removed my hand really fast and, to my surprise, the lights started to vanish slowly. I touched the soil again and some lights appeared here and there. That stuff was alive!. It was an E.T. moment.
That day I learned that even the humble earthworms can be awesome, specially the bioluminiscent ones.
