Why is it easier to push something into something and hard to get it out?

Question

Like how come i can get a ring on no problem, but need to get out butter or something to rip it off, almost degloving my frickin finger

Answer 1

Well in the case of the ring. When you slide it on the skin on your finger stretches. When you try to pull it off the skin bunches. Did you not see this?

Answer 2

Well, with arrow heads or fishhooks, there are barbs that slide in easily one way but then get stuck if you pull them the other way. Maybe with some substances, you line up the little pieces going one way and then when you try to pull them out, it's like a fishhook. Kinda like when you open a box of cereal, it fills the box evenly, but then after it's open, the bag gets all saggy and the cereal pushes out the sides of the box.

I think it's about settling particles. As far as rings, your knuckle's probably swollen a little, and then when you push the ring over, it pushes the swelling aside a little, but then, it settles back and it won't push the swelling back the other direction. Personally, I've broken most of my fingers and the lower joints are fat and swollen, so the joint where I wear the rings is fatter than the joints and I never have any trouble taking off rings.

Not that I suggest it or anything. But that's what works for me.

Answer 3

try passing your finger through a demagnetizing block....

but seriously folks...

theres more fat on the base of a finger than the middle or tip.
also its all in your head. why? because if the ring didn't go on, you never know it won't come off....
