(Newser) – A network of oil storage tanks hidden in the hills of Scotland during World War II is officially the most echo-friendly man-made structure on Earth—and it's not close. The report from a blank fired into the tanks reverberated for a stunning 112 seconds, the Independent reports. The previous world record was 15 seconds. "My initial reaction was disbelief," says acoustic engineering professor Trevor Cox. "The reverberation times were just too long. I knew immediately we had a world record."

Cox saw the site on TV, and had to investigate. "There are no doors, so I had to be pushed in through the 18-inch diameter pipe," which was covered in oil, he explains. "It was like going underground into a Bond villain's lair. But never before had I heard such a rush of echoes." The BBC has images of the site, which was decommissioned after the Falklands War. The previous record was also set in Scotland, at the Hamilton Mausoleum in Lanarkshire in the 1970s.

In 1981 we washed cars, did bean suppers, begged at the Kiwanis, Rotary, and Lions and raised enough money to send us high school seniors to Los Angeles. We then broke into groups to tour certain places. I chose a group that did Capitol Records. We visited the echo chamber in the sub basement. It was totally acoustic and used a rail system to adjust the position of the mics and speakers. The one I had at home was a box with springs and a pickup. Capitol's was often heard in their records of the era.

That's nothing. I'm still hearing the echo from my ex-wifes vagina. We divorced 15 years ago.

Yep. I'm moving there and opening a rave club. With accoustics like that, I can just use an iPod and some desk speakers.
