It appears broken because of the reflection of the object and it's from the other molecules hitting the water which causes a bend like appearance to happen the light bends.the light bending is called refraction.
The spoon cools the hot water slightly just before it hits the glass. It's just enough to keep the glass from cracking from localized thermal expansion. Thermal shock on the glass is reduced slightly and spread out over time. It would be similar to hitting the glass with a metal hammer versus a rubber mallet.
When we pour very hot water into an empty glass, the inner surface of the glass will expand as matter expands when heated. But the inner surface of the glass will expand more than the outer surface of the glass because more heat is applied to the inner surface of the glass. Thus , causing uneven expansion and the cracking of the glass. Hence, when a metal spoon is placed in the glass, it helps to conduct the heat quickly away, and to prevent it from cracking.
It cracks as the inner layer expands more quickly than the outer layer and will push the outer layer and it will crack. When you put a metal spoon in it, the heat will be conducted away from the spoon to the surrounding as metal has a good conductor of heat due the the freely moving electrons and thus the glass inner surface will not expand so quickly and will not crack
The spoon absorbs the heat when you pour in hot liquids.
Because water bends light, thus making the spoon appear distorted.

It will crack because like clay in a hot oven, if all the spots are not covered correctly, it will have a chance of cracking, but when the hot water gets into the crack, it will start to make it bigger. If the expansion is uneven, the glass will break and I don't understand why it won't break with a metal spoon.

One way to fix a crack in a glass globe is to bring it to a glass blower. It may be fixable that way. However if the crack is too big or deep, it may be better to simply purchase a new one.
This depends on the type of window/glass as some glass is thermally treated. However, stress in the glass from contraction/expansion can make a noticeable crack. Heat alone will not crack glass but it will, over time, melt it.
due to refraction of light..
you can if you put a spoon it the glass first before pouring in the hot liquid, otherwise the glass might crack
As the metal spoon is a good conductor of heat and because heat travels from a hotter reigion to a colder reigion,the metal spoon will conduct heat away from the hot water and thus,the emty glass will not crack.

The metal spoon has the capacity to absorb some of the heat of the very hot water, but not very much. It only makes a small difference.the crcking cracking crack
The answer to the riddle is that you can put a crack or chip in a glass, but you can "never" take it out.
If this wine glass is made from common glass will crack.
yes. i do it all the time ------------- If this wine glass is made from common glass will crack.
bakeing pouder and a little watter then put it on a spoon and light a lighter under it it will turn it into crack :)
You put it in a small glass pipe and heat it with a lighter. Glad I could help :)
Highly unlikely.
a crack table u dont have 2 put glasstable because a wood table cant crack
the powder will just sink into the bottom unless you mix it with a spoon!
