The paper becomes semi-transparent.
Nothing happens. I have amber and wear it with wool and other clothing. At the very most there is friction.
yes it is
All materials have a property called the coeffecient of kinetic friction. When this property is high, a higher friction force resists the motion of objects across the surface. Sandpaper has a higher coefficient of kinetic friction as compared to something like ice. This is because ice is smooth whereas the surface of sandpaper is very rough which increases the friction it causes.
no
shes not your mum if she is asking you to rub her nipples that would be wrong.
uh...no.
Hughstun Homan hates it and wants to rub his nipples on it
Rub it with sandpaper. Skin is made of wood and sandpaper rrmoves the burrs and defects.
they can rub their nipples
rub vinegar on them
The type of friction that occurs when you rub sandpaper against wood is kinetic friction. This friction opposes the sliding motion between the sandpaper and wood surfaces and is responsible for generating heat during the rubbing process.
That happens to me all the time! The best way to make it stop is if you gently rub a little bit of lotion on the nipple. I hope i helped :) !
Friction
they rub their nipples until they bleed
Rub it with very fine sandpaper (400+)
You can stimulate your nipples by exposing them to colder conditions (such as ice, or cold weather). You can also rub them, or pinch/bite them.
