I've done it again, folks. I've gotten some things wrong on Skeptoid. And so, as I always

promise, I'm now going to issue the corrections with thanks to those who caught them. We're

going to get started with a correction to the episode about a mysterious, impenetrable,

metal sphere, which was believed by some to be some kind of alien device with mysterious

capabilities. That's today on Skeptoid.

You're listening to Skeptoid. I'm Brian Dunning from Skeptoid.com. Full of hot error.

Once again, it's time for a round of corrections to past Skeptoid episodes. These episodes

are fun. Many listeners either love them or hate them. They're not a new single subject,

but instead they go back and revisit a half dozen or so previous episodes to either

correct an error or provide some newer information that may impact the conclusion. I always really

enjoy these, not just because we get to revisit previous subjects I've come to love, but

also because they improve each episode with better, newer, or corrected information. In

that way, these episodes are the heart of what Skeptoid is. When we learn something new,

we adapt our understanding of a subject to accommodate the new information. So, let's

get started.

Episode number 334 was about a famous urban legend concerning a mysterious metal ball

known as the Betz-Mysteriesphere. It was a 10 kg, 20 cm hollow steel ball, claimed

to have all sorts of strange powers, powers which sadly failed to be replicated under

controlled conditions. It was ultimately identified by a sculptor who had lost it along with

several others about where the Betz family found it. It had been given to him by a friend

who worked at a company that employed a number of great big industrial valves, which I described

in the episode as ball valves.
