I wonder how different the world would be if farts were visible.
How would it look if a cloud of green gas emanated from a world leader during an important meeting? Or a blue cloud from your favourite pop star during a concert?
No longer could school kids pretend it wasn't them during class. And people would probably be physically ejected from elevators.
But the possibilities for humour would be endless.
My boys would then try to be even more annoying than they are now with their farting nonsense! To them its a game. (groans)
