I was just as intrigued as Destin was to learn that a tattooing needle doesn’t come to one point — the end looks more like a bundle of arrows.
The needles themselves aren’t like the hypodermic ones that would inject a vaccine into your arm, tattooing needles are there only to puncture skin. Once there are hundreds of tiny holes leading down to your dermis — the layer of skin between the epidermis (outer layer) and subcutaneous tissues — the ink between the needles is drawn into them by capillary action. In short, the surface tension and forces holding the ink together encourages the ink to seep into the holes left by the needles.
To understand how this is done, the video below captures the process in slow motion.
