Your eye is interpreting the path taken by the light that reflects off the pencil.
due to refraction If the pencil is vertical, then it shouldn't look broken.
Because of refraction of light
-the pencil looks broken & bent in water. - the pencil looks bent, because of the refraction of light, that causes that to happen. -pencil looks really thick, in water.
Physically, the pencil remains a straight pencil. Optically, due to the refraction effect of water, the pencil will appear to be bent.
because a yellow pencil can only reflect yellow light and that yellow light is what you see from a yellow pencil.

More or less the same difference between a broken pencil and an unbroken pencil, except the bone has the potential to heal.

First, remove broken pieces slowly. Then obtain new pencil and try to relax this time.
That is a very sharp response...Writing with a broken pencil is pointless...
broken pencil
It's a play on words. It would be pointless to try to write with a broken pencil because the pencil lead is not pointed.
Yes, a pencil can be broke by the force of Ice. This has been tested by a man leaving a pencil wrapped in tinfoil and covered in water, then left in a fridge. They waited and when they pulled it out the Pencil has been broken by the covering tightening over it and the Ice pressure, compressing it. This is how a pencil is broken by the force of Ice.
