Sometimes, science is all about the mind-aching big picture. Like the idea that our Universe is just a giant hologram, or that we’re on the brink of discovering a new particle that might break physics. Or that we might not actually have as much free will as we think…

Those are really exciting concepts. But then there are other times when you come across a day-to-day application of technology that’s so simple and yet so important, it reminds you what all this innovation is about. Case in point: that ubiquitous hole at the top of your BIC pen cap.

You’ve probably never given it much thought, or if you have, you’ve probably brushed it off as some random design feature that regulates air pressure or stops ink from drying out. And, yes, having a hole on their does allow you to close the lid properly without the air pressure issue. But it also serves another simple yet ingenious purpose – reducing the risk of choking deaths.

Turns out it’s not just us who love chewing on pen lids – a whole lot of people do it, and that can lead to lids getting accidentally swallowed and lodged in the wind pipe, with potentially fatal consequences.

By simply adding a larger hole to the top of the lid, pen company BIC increased air flow and the chance that people would still be able to breathe even if that happens – a design feature that, quite literally, saves lives.

“In addition to help prevent the pen from leaking, all our BIC caps comply with international safety standards that attempt to minimise the risk of children accidentally inhaling pen caps,” the company writes on its website. “Some of these vented caps, like that used for the BIC Cristal, has a little hole in the top to comply with the existing safety standards.”
