This is a hypnotizing video (be careful watching if you're easily hypnotized because somebody could snap their fingers and next thing you know you're quacking like a duck in front of your entire school and you get so embarrassed when somebody tells you what happened afterward that you have to change schools and try to convince your parents to sue the hypnotist the student government hired for the assembly) of a 4-axis CNC (computer numeric control, basically computer automated) lathe cutting a wavy pipe from a straight pipe. Not a smoking pipe though, just a wavy piece of metal. I think it's going to be part of a sex toy.
Hit the jump for the video.
Thanks to hairless, who's about to be fingerless too if you don't stop toying around with that table saw.
