Answer:
I am the reaction after enjoying soda.
I have a little house in which I live all alone. My house has no doors or windows and if I want to go out I must break through the wall.
What is that you will break even when you name it?
It flies around all day but never goes anywhere? What is it?
I am what bring things together. Without me everything you see would be a total mass or debris everywhere.
Give it food and it will live, give it water and it will die.
