Have you ever seen a tattoo needle up close and personal? They can be scary or reassuring, but Gavin Free and Dan Gruchy, the Slow Mo Guys (previously at Neatorama), take the process a step further by recording a working tattoo gun installing ink in transparent ballistic gel, so we can see macro slow-motion video of what it's doing underneath the skin's surface.
Gav and Dan say they don't have any tattoos because they're not brave. We have seen their videos, and know quite well what ridiculous stunts they pull and what bravery is necessary to do them. But after recording what a tat gun does on a macro level, they are even less likely to get a tattoo in the future. I'm with them. Like I told my kids, "Life has enough pain without paying for more." Their father had plenty of tattoos.
This video has a sponsor message from 8:20 to 9:30. The rest of the video after that is outtakes. -via reddit
