Trivia Fact of the Day: pen tops

by Skip

WHY PEN CAPS have holes in them. “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.”
