It is Thursday the 9th of August 2018 and you're listening Skeptics with a K the podcast for science reason and critical thinking.

Skeptics with a K is a production of the Merseys

Skeptic Society a non-profit organization for the promotion of

scientific skepticism on Merseys

around the UK and internationally. I am your host Mike Hall with me today is Marsh

Hello and Alice. So, so St. John's, down the road has got a 9D, a 9D ride. Right. Okay. Okay. Okay. So the D stands four dimensions. Are you sure it stands for

dimensions? I mean they don't say that explicitly. It's not River D's. It's not like

Yes. And even that the photograph persists through time.

Or you're sitting, you're watching a line for a long time.
