Grease pencil, you pull a tab and the things unrolls.
nice alternative, and that'd make great sense except... now you have a bunch of long strings of grease covered paper floating about the cabin.
so no. no thanks.
No I mean that's literally what they were using not graphite.
having used grease pencils before, no thanks, due to the remainder of greasy paper you unwind as you use it.
They aren't suggesting using a grease pencil as a better alternative to a graphite pencil, they are saying that the Russian cosmonauts used grease pencils before moving to a pressurized pen.
You don't need to say "no thanks" to it, no one is suggesting using it. The first comment was ambiguous, but your response to this one is just baffling.
no thanks.
I'm pretty sure astronauts are trained on the usage of garbage receptacles.
side note, mechanical grease pencils are literally some of the best goddamn marking tools ever invented by humans, and the fact that we’ve moved away from them as a standard in favor of sharpie-style disposible markers is APPALLING.
there’s myriad “industrial” markers you can buy, which are generally especially well suited to one specific inclement situation. low temp markers won’t freeze, but will often bleed and feather. oil-proof markers will write on a slippery surface, but will smear and take ages to dry proper (RIP lefties). paint markers can write on anything, but only as long as the surface doesn’t immediately destroy your nib and prevent future wicking.
grease pencils (quality ones at least) go down like a crayon, stick to ANYTHING, and generally won’t smear at all. obviously no one should be writing their thesis with one, but they can do pretty much everything we use permanent markers for. they’re also cheaper and produce far less waste.
as far as i can tell the biggest downside is there’s a smaller profit margin for the manufacturers.
Im a fan of grease pencils yeah, especially for marking on windows. I'm a mechanic and sometimes I just do the diag notes on the cars Windows or if laziness.
