Elia is a sculpture in Denmark created by Ingvar Cronhammar and installed in 2001.
The structure is an imposing spherical dome with a diameter of 60m and a central chamber surrounded by four large columns, each reaching 32m high.
But this otherwise odd industrial artefact in the middle of a Danish field has an incredible quirk:
At random intervals, it shoots fire.
These eruptions, as they're known, are very rare - lasting a mere 25 seconds and occurring weeks to months apart, as determined by a computer.
Here, your task is quite simple.
Clicking the picture of Elia above will take you to a website that will display the final coordinates for ten-minute intervals spaced at random durations (24 hours at most).
All you have to do is wait for it to ERUPT.
