I get this every day! It's a combination of several joints in my spine cracking, plus I'd imagine the articulation between my spine and skull cracking as well.

I love to do it on the tube or in a shop to watch the non-crackers cringe!

hi guys! new here.

I can crack:

my jaw on both sides;
my neck (at full left/right rotation, then looking upwards);
both shoulders;
both elbows (as many times as I want - this is my favourite one to do because it makes a really loud noise and freaks people out :lol:);
both wrists;
both thumbs;
all my proximal interphalangeals;
all my distal interphalangeals;
some of my metacarpophalangeals;
my back (not sure which vertebrae :?);
my left hip;
both knees;
both ankles;
my right foot;
all my toes!

I'm currently trying to develop a rhythm from the cracks so I can whip it out as a party piece. I study medicine and have trawled the journals and spoken to orthopaedic surgeons, but they don't know anything about it! It's so much fun to crack my middle finger in a quiet lecture or exam hall and hear it echo.

Any other crackers get stiffness that is only relieved by cracking? Such a relief…

good to meet fellow crackers/poppers/clickers
