#8 - It's the sudden temperature change that caused the cracks, not the heat. Glass is made in extremely hot temperatures, so withstanding any heat that the OP could have caused is not an issue. OP, when you suddenly and drastically change the temperature of the glass, cracking is inevitable. This is why it's also a good idea to rinse glasses with hot water before putting boiling liquids in them.

People are that retarded. My ex-in-laws were from GA and they used BOILING water. They offered to do it to my car. I had my car thawed and scraped before their water even started to boil. How they never cracked a window is beyond me. Their logic was because it wasn't as cold consistently down there it wasn't as much of a shock. I gave up trying to explain that frozen is frozen and boiling is boiling no matter your relation to the Mason-Dixon line.

#13 i think that area of france is the default location if the OP doesnt state it and its a pretty damn stupid thing to do, but why does everything stupid have to be called fake, 6.8 billion people in the world some of them are gonna be stupid or just make stupid mistakes, if they didnt there'd be a lot less fml's in the world

Do the people on this site not know that the people who created this site are French? All of them! Look to the right of the screen: Maxime VALETTE, Guillaume PASSAGLIA, Didier GUEDJ...

I've been to France, I used to live there. They are stupid. Americans are too, don't get me wrong, but as a whole French were just lacking common sense. Maybe that's why in WWII they built a giant wall to stop the Germans and then watched as they flew right over it... And took over the country in a few weeks.

If the window is cold and you throw hot water on it the water heats that side of the window up very quickly, which also causes it to expand. Since the other side of the window is still cold and not expanded, the window basically destroys itself.

@ Blue Coconuts: Germany took over France in WWII......wow!!! Yet somehow at the end of the war Germany was pretty much destroyed and signed the ECCS Treaty in order to receive money from Italy, Luxembourg, The Nethelands, Belgium and.....FRANCE! Open a history book every once in a while!

its not the fact that its water. if you have a really cold glass, and you pour hot liquid in it, it will crack. the instant heat shocks it because it doesnt have time to expand gradually.

True that. It seems like most of the people that call other people stupid are morons themselves. Back to fifth grade science class people. Remember those things called molecules? Its simple. Molecules expand when you supply heat and contract when cooled, everything is made up of molecules and atoms. Everything. Glass can withstand constant gradual rise in temperature. What it can not stand (besides idiots) is rapid heat which causes some molecules to expand faster than the other resulting in bro

Oh noes! You mean that this summer, when my car windshield gets hot from the sun, it will have a problem holding all that heat and it will crack?!?! Whatever will I do?!?!?

if that's true, are you saying it is easier to crack a coffee mug by putting boiling water in it than a wine glass??? just wondering, cuz now I gotta try it to see if it's true XD.
