Now given his mailing address, perhaps we shouldn't be too surprised if the
answer's 'no'. However, there are more things in heaven and earth... For
example, next time you find yourself in the dark with a self-sealing
envelope, one of the ones with the tacky strips you push together and don't
have to lick - and I promise I won't ask you why you're there as long as you
don't ask me how I know this - seal it up and then rip it open along the
strip. You should see small flashes of light as the two tacky strips
separate. You may have to try it a couple of times.

Odd, isn't it? That's the only thing that stops me pointing at this post
and hooting like an owl that's been to the pub.

Perhaps it would. Off you go then, there's no shortage of them.

Or start googling for the term "triboluminescence". I only know it as I
asked about the sparkly envelope thing several years ago, in another
newsgroup.

Triboluminescence

Luminescence (light) triggered by mechanical energy or
electrical energy from a mechanical action such as friction.

You can get stones to do it as well. But it has to be the
right sort of stone, and Hawkin's Bazaar used to sell a pair
of 'em together in a placcy bag so that this sort of
experiment could be carried out in the privacy of one's own
understairs cupboard. I've just looked at their current
catalogue, however, and can't find it, so perhaps this isn't
the time to put them on your Christmas list.

We've got some "Glowstones", they're a bit sad and pathetic but do produce a
bit of a glow if you take an optimistic stance on the definition of the word
glow and consider 10 minutes rubbing a couple of stones together to be time
well spent. Can't get anything out of my Karrimat as per the original post
but the envelope thing works quite well, haven't heard that one before. The
usual thing quoted for demonstrating triboluminescence on US websites is
crunching sweets called "Wintergreen Lifesavers" which apparently produce
some descent sparks. Don't know if any sweets available in this country are
any good, look for some with methyl salycilate in them.

Many things will produce static electricity sparks you can see in the dark,
the easiest way to amuse your kids for 5 minutes is probably to get them to
rub a plastic supermarket bag over their head. And for more light related
cutting edge science, once they're bored with that you can let them connect
various pickled vegetables up to your mains electricity supply which gives
some interesting effects. Make sure your other half isn't watching
something vital to their happiness on the telly in another room first.

You don't need to buy them, they're just quartz crystals that you can find
in the Dark Peak and elsewhere. On the Cairngorm plateau you can get lumps
the size of tea chests, but they're a bit difficult to clash together!

there are bioluminescent Fungi which could well have been inhabiting your
rolling mat at the time. and just possibly there bioluminescent properties
were triggered by the smoldering hot rocks from the joint you were smoking
at the time.

I mean it could be true, who can really say that they no what would happen
if the two were to mix.

Perhaps this post may be better answered in a scientific group but I
am more Interested In first knowing if anyone has seen the green glow
from rubbing the Karrimat. I am not jesting and two friends
demonstrated the same thing while we stayed at Bala on an autumn
weekend in `87. I believe we witnessed inert gases being excited by
electrostatic charge from friction but the effect was impressive to
say the least. You could see the glow reflected on the tent walls and
sometimes what appeared to be green sparks coming off the fingers. Now
quips about what we would be doing rubbing insulation mats aside I
wonder if other people have seen this. When I witnessed this the
weather was wet and slightly misty. I have tried to repeat the effect
from time to time and have not seen the like of it. I got a suntan
while staying in Bala one week; I even have pictures to prove it that
makes my camping mat tale look like gospel eh.
The friend who discovered this trick is truly gullible and as he had
been camping in the lakes during May of `87 we told him the effect was
"caused by Chernobyl". It must be said he was quick to question why
the same effect could be observed by owners of mats much less traveled
than his own, those not lucky enough to have drank lots of fresh
rainwater while having no clue as to events In Ukraine. Bit off piste
there but you get the drift, any scientific walkers please explain,
anyone who has seen the magic glowing mat trick do tell. Why be
rubbing a Karrimat? A Vesuvius of a joint had dropped boulders of
glowing debris on such a mat so there.

My pal would gather decent sized lumps of quartz for a rockery he wanted
to build. On one occasion when we had quite a few lumps in the
Landrover, on arriving home he loaded them into a barrow, wheeled them
to his pile of quartz already collected and tipped the barrow onto the
pile. You should have seen the sparks that came off that little lot. I
may add it was dusk at the time and made the display more dramatic.

Thanks for the input though it looks like the mystery will remain
unsolved. I know the effect of Quartz crystals and the pleasing sparks
when struck against each other but what i witnessed was a goodly green
florescence. I have a Thermarest mat now and the mystery of the
Karrimat shall remain "unexplained".
Everbody please enjoy their winter walks, the flies have gone,
the coach parties too. So its time for those who enjoy the hills and
moors to get out there!

The first time I noticed this was when I was removing the sticky tape at
the end of a roll of film I was developing in the dark room.
I don't think it was enough to fog the film. :-)

It can be - it's a known problem where you get lightning flash marks on the
end of the roll.

Yep, I've seen this loads of ties. Doesn't seem to be linked with any
particular conditions.

Cheers Blippie,
now I can visit the science groups and annoy them with my posting!

Frictional processes cause very high temperatures at a
microscopic level (e.g. two pieces of polished steel will immediately
weld together if moved against each other in a high vaccuum)

Really? Is that theoretical or practically achievable with a £450 rotary
vane vacuum pump, a polishing wheel and a hastily bodged together bit of
kit? (He says optimistically).

Interplanetary space is a high vacuum. Most space activity is more of
a high Earth orbit though. I don't know what the level of vaccum is
for such orbits, although this info is probably readily available via
Google. I imagine that NASA (and the satellite industry) will take
into account all known vacuum phenomena in their designs. Vacuum
effects are really a topic for a different newsgroup though, I notice
that posts (mine also) are straying away from the original topic (i.e.
Karrimat Mystery).
