The flame

With this blip I will break with the last 3 consecutive blips about healthy food. Anyway, thanks for your comments!

But what is this exactly now?
This is the flame that allows me to take a hot shower every day and therefore definitively deserves at least one appearance here. :-)

My big thanks are also going to Prometheus (some thousand years ago) for stealing the fire from the gods and bringing it to the humans. You did a great job!
Didn't you agree.
