Air condition is the invention that I like the best as the weather is very hot recently.
It is very cooling. A air condition will alway place on the higher position of the room as the cold air(denser) will sink,the hot air will rise and this continues until the temperature of the room is the same.

This fascinated me as when I sleep I can have cooling air condition to enjoy.
And I wonder why it can produce cold air until i have a research on it.
It also help us to cool down when the weather is very humid and hot.
We also like to hang out in the air-condition room as it is very enjoying.
