It might be a quantum physics thingy

How does poo smell?

I mean, I know WHY poo smells, I've read the scientific literature. (And it's brown because bile is a purplish color, did you know that?)

Let's say you'd poo'd and there is poo in the pot - it's completely submerged, nothing sticking up above the water.

Now, smells are actually just tiny particles of the item (so when you smell food, you're actually sniffing up teeny airborne food particles - it's the same with all smells).

With the submerged poo, the particles in the air should disperse quickly, but they do not. If you should somehow forget to flush and come back later on, the room still smells of poo. But the particles should have dispersed, and without bubbles or particle action of some sort, there shold be no smell. Mebbe there are microbubbles that I can't see?

A fresh twist on a classic

You know the old saying "If a tree falls in the forest, and no one is around to hear it, does it make a sound?"

From a very young age, I've always thought this saying was BS. Of course it makes a sound! Sound waves are made up of vibrations, duh. This is simple physics.

I think a much better angle would be to say "If the swamp belches up gas, and no one is there to sniff it, does it make a smell?" since smell is a perception, and sound waves are not.
