that creaking is due to slowly moving your fingers while  slightly dehydrated. the lack of adequate water causes your joints to be slightly less "lubed" basically and  slight movements will give a noticeable resistance in the form of the "creaking" while sudden movements will not because the stiffness is countered by added bloodflow. - Mr. Schumacher Physiology Major,  high school health teacher.

I've asked what the creaking was before to a health teacher. put simply. drink water that's not a psiball thats muscle and joint stiffness.
