The science behind these seemingly banal objects is surprisingly fascinating!

We don't give much thought to ballpoint pens — you probably don't even know how many are hidden in your desk. As long as they work and are reasonably cheap, that's all that matters. But did you ever wonder how exactly the tip works? It turns out the ballpoint is ingeniously designed to evenly deliver fast-drying ink without gumming up at the tip or letting the internal reservoir dry up. Also, everything looks cooler when you zoom in really close.
