Stupid question...
Ok .. I'm getting bored waiting for someone to update a topic so I thought I'd start off a new one.
So... thinking about how wonderful the house smells on brewday has led me to consider this...
What is the speed of smell?
The speed of sound is 340 m/s, light travels at 299792 km/s, teeny-weeny little smell (aroma) (see what I did there?) particles must travel at some rate of knots too.

I don't think the smell will move at all.
It's all about air currents and diffusion.
1 Why do we smell bread baking throughout the house? The answer is diffusion. A good way to describe diffusion is the moving of molecules from a place where they are concentrated close together to a place where they are less concentrated or farther apart. When molecules are spread out evenly, diffusion seems to stop.
2 Smells travel in the air by diffusion. Because molecules are always moving, some molecules leave the bread as it is baking. They are vented with the excess heat from the oven. These tiny molecules of bread travel through the air throughout the house to our noses.
3 Have you ever passed by a bakery and noticed the delicious smells down the street from it? If the wind is blowing, there will be more mixing of the molecules in the air. That can either make the smell reach you sooner, or it can spread the molecules out so that you don't notice the smell as much. Since our brains are used to the smell of air, we don't smell the oxygen, nitrogen, or carbon dioxide. Instead, we smell the other molecules mixed with our air. This is why we smell the bread baking, smoke, perfume, or other smells.

Tell you what I should be used to the smell of my dogs farts by now but they still stink and they travel at the speed of light.

I was thinking a pretty similar thing about Eleanor's nappies. I'm sure it's possible to smell them before she's filled them!

Sorry to have lowered the tone Varnish by the way. Great info as always!

:o) Greg .... I think I lowered the tone by asking the question in the first place... The title said it all really!

I think it was a valid thought.

Maybe in retrospect ... but only because Varnish came up with such a valid answer :o)
