Well known fact that light travelling at 300,000 km/sec passes through glass of  beer,
slows down , then reverts to full speed on emerging from the glass. In the experiment
carried out recently it was all in a vacuum, though since university staff were there
hard to imagine no beer  involved........

Where did you find that fact Agrippa - have you got a link to the experiment? If the experiment was in a vacuum how do they know that the beer slowed the light down? Perhaps after every experiment they drank a beer and by the time they'd finished things just seemed a bit slower!

Probably cold lager goes through students at the speed of light....

No wonder they can't manage on their grants/loans etc...

Its probably because they were using low energy light bulbs which, as we all know, take ages to light up!!

Actually they light up quite quickly.  It appears slow due to the fact that they release low energy light which is quite sluggish and takes longer to get out of the bulb.
Apparently low energy light is much cheaper to make and store in the bulbs which is why there is a push to make all lighting low energy,  government is in the pocket of major manufacturers.

And it is a proven fact that all electronic devices operate by the internal flow of smoke.
When the smoke escapes, the device stops working.

Someone else who's fallen for the cunning government counter-propaganda. Surely everybody knows that so-called "light bulbs" are actually "dark suckers" which work by sucking the darkness out of the surrounding area? It's the forces of darkness in their black helicopters conspiring to push their low luminosity agenda upon us.

Hey, do any of you remember a forum member called "Railsquid".
Seem to remember a post, something about dark forces and gov propaganda, but nothing since.
Can't find a trace of such a member on the site.  Strange thing is, every time I do a search for the name I get booted from the site.

Well probably imagined it all;  old age, you know, does trick the mind.

You don't need to be afraid of the dark....


You need to be afraid of what is hiding in the dark   

This is getting spooky.
To change the subject - here's another interesting fact.

Why do people clink their glasses before drinking a toast?

BECAUSE:

It used to be common for someone to try to kill an enemy by offering him a poisoned drink.  To prove to a guest that a drink was safe, it became customary for a guest to pour a small amount of his drink into the glass of the host.  Both men would drink it simultaneously.  When a guest trusted his host, he would only touch or clink the host's glass with his own.

A common story. But not necessarily true... or at least, without any evidence to support it.

Some might say university staff exist in a vacuum but I couldn't possibly comment

Reports of my demise are premature, and there is no factual basis to the rumours that I'm merely a figment of your imagination.

Meanwhile, back on topic, the origins of the word "ketchup" are unclear, but the best theory is that it derives from a Chinese word.

I'll elaborate later but there's a hammering at the door

Interesting link Nemo but again not necessarily true without any evidence to support it. That's the problem with all urban myths - difficult to prove.

It is a known fact that 93.74% of all facts and statistics quoted on internet forums are made up by the poster.

Now, where is that "irony" smiley???
