Sometimes science is associated with amazing pictures. Such as the idea that our universe is just a giant hologram or that we find gravitational waves through collisions of neutron stars. Or we really can't
You know, science is mostly about big, astonishing things and innovations, like discovering that the earth is just a giant hologram, or a gravitational wave created by the collision of a neutron star. That's an interesting thing, right? But there are some other things that are not overly arrogant, but very important, but always go unnoticed, even though some of them are our usual everyday use of technology. Have you ever wondered why most pen caps have holes in them?
Very few pen users believe that the holes dug in each pen cap are simply a random design feature that regulates air pressure and also prevents the ink from drying out. Yes, the hole in the pen cap allows the cap to close properly, which eliminates air pressure problems. But the holes have a purpose more than that. They serve a purpose you wouldn't know if you didn't read the next few words - it reduces the risk of choking.
Not only do we love chewing on the cap, many do, and this process can cause the swallowing and cap to stabilize in the windpipe. This can have many fatal consequences.
So, adding a bigger hole at the top of the lid would increase airflow and the likelihood that people could still breathe even if such an event occurred. Isn't it amazing how this hole saves lives?
