Some
things should just be common knowledge by now. The Earth isn't flat. Nope, your
hair and nails don't grow after you die. The holes at the top of Bic biro pens
are there so that, if you swallow one accidentally, you can still breathe and
won't choke to death. It's debatable whether that last one there is common
knowledge or not. A quick Google search of the fact, rewritten as a question,
shows articles addressing this point going back several years, with the latest
(re)appearing just this week over on ScienceAlert.
We suppose it's one of those things that come up from time to time, like what
would happen if you attack Yellowstone with a nuclear weapon (not much, as it
turns out).
If
you jump over to Bic's website, under their FAQs (frequently asked questions),
it quite clearly states: "The reason that some BIC® pens have a hole in
their cap is to prevent the cap from completely obstructing the airway
if accidentally breathed in. This is requested by the international safety
standards ISO11540, except for in cases where the cap is considered too large
to be a choking risk."
That's
rather lovely of them. In appreciation of their want to not kill off their more
clumsy customers, we thought we'd share a few more random facts about Bic that
are probably going to come up in a pub quiz one day. Did you know, for example,
that each Bic ballpoint pen can produce at least 2 kilometers (1.2 miles) of
ink before it begins to run out? In fact, in 2018, 7,250 kilometers (4,505
miles) of writing tests on such pens were carried out on ballpoint pens, gel
pens(中性笔), and rollers to make sure they worked
to the highest standard.
The
best part of the Bic site, however, is this rather curious fact: "100
percent of pen balls are made through a highly-controlled process." As
opposed to a highly uncontrolled process, involving explosions and bouncy
castles and total chaos, we suppose.
