For as ear-piercing as ambulance sirens are, you’d think they’d be better alert systems. Truth is: they’re shockingly ineffective.

Yeah, you can buy those blue Bic pens in bulk if you want—a boatload costs about as much as your morning coffee. And all pens are pretty much the same, right? Of course not.
