Yikes! Ok, here's the thing. This video is incredibly informative if you want to learn about the process of tattooing, the tools they use and how they function, and the science behind the art. However, the parts where they show a tattoo being done in slow motion may possibly make your skin crawl! It's so nerve wracking to watch the needle poke in and out of the skin in slow motion, but it's so cool and fascinating we can't look away!!!
