American--My country is the coolest atmosphere.
I can prove.If you fill water in a vessel, it will turn to ice within three hours.
Russian -So what ? Please visit my country and fill water in the same vessel,get ice within one hour only.
Indian-Absolutely not coller than ours is. In India , in winter, if you go on terrace of the first floor pour water from there on earth, it will turned to ice and will tilt itself in between the ground surface and the floor terrace.
All the previous three- what a boasting! According to gravity law given by Newton, everything will fall down towards the earth.

The Indian- That is why I am insisting that the coolness is so high that the gravity law ,too, gets freezed.
