(UK only) Question about Tomorrows World 1980's compact disc demonstration?

 Does anyone one remember The Tomorrow's World demonstration with the first compact discs?
As I recall, they poured honey and dust onto it, gave it a quick wipe and it played without a problem.
I don't believe my modern cd would stand up to such treatment.
Was it a fixed demonstration or were the first cds a bit more robust?

Answer on the other topic, but I think it may have been jam rather than honey?

What they DIDN'T do is scratch them you'll remember
I'd thought it was sandpapered first, and tonight considered that Philips led them through the demo: sandpaper, jam (the jam fills-in the scratches). After all they're just presenters, they know nothing of new technology.

Meh.  Honey is water soluble.  If you wipe it off while it's still wet, it'll clean up nicely.

In the '80s cds weren't as dense as they are now and a scratch of dirt didn't mean as much as it does now.  Still I've scratched a disk just to see how much damage it would take before it would quit reading and I was surprised that I scratched it over a dozen times before it quit working.  The scratches went from the hub to the edge.

Can't do that with a dvd, sometimes a finger print will make them read as errors.
No, it was real. An enormous amount of "capacity" of a disk is error correcting codes, and CDs are VERY tolerant of faults.
