METAL PIPE

One schedule for the whole planet.
Nobody knows when — not even whoever put this here.

• Every listener on Earth hears it at the same instant, regardless of timezone.
• Timings come from a public randomness beacon that does not exist until seconds before it fires. There is nothing to memorise and nothing to leak.
• Gaps run 4¾ to 29 minutes, mean ~13 — the same distribution as the source video.
• Leave the tab open. Turn it up. That is the entire game.
