How can we quantify fluffiness?
« on: 24/10/2011 16:01:02 »
Angela Fraser  asked the Naked Scientists:
   
Is fluffiness something that can be defined and measured? We say something is fluffy and that things are fluffier than other things? But other than resorting to referring to softness or density of fur on an animal etc. can we express this specifically?

What do you think?

Isn't fluffiness usually measured in bunnykins?  (sorry  [;D])

Angela, it seems you have stumbled accross an area that is in need of definition.  Maybe you should create some kind of scale of fluffiness...  [;D]

Some things that are fluffy; clouds, animals, bellybutton fluff, pancakes, bread!

I suppose we could use some sort of thermal insulation measurement, because that is why a lot of the fluffiness exists in nature, but I still prefer units of bunnykins.

(I wonder if SI would go for it?)

Would a bunny be one unit of bunnykin....  [;)]

I wonder if there's a planck fluffiness?  Its got to be a lot smaller than a bunnykins.

Oh please, PLEASE, all of you, try to be serious!

EH! WHAT! Is that me urging others to be serious?!?!?!

Something has gone seriously wrong here.

Sadly, the man who perhaps could have answered your question, is no longer with us. I refer, of course to Alan Freeman.

Perhaps a fluffometer would be a device to measure the volume of air trapped within the fabric of the fluff. Fill an air tight container (of a known volume) with the fluff to be defined, so that it touches, but is not compressed by, the bottom, sides and lid. Use a vacuum pump to remove the air and measure the volume of air extracted from the container.

The equation would be:
Known volume of air in the empty container (S) minus extracted volume of air (E) equals fluffiness (F).

Just a minute....... Would a Tog Rating do much the same thing?

If you'll excuse me, my brain hurts. I must go lay down in darkened room for a while.
If brains were made of dynamite, I wouldn't have enough to blow my nose.

If you are thinking about pillows.
There would be a couple of important quantities that could be measured.

Density.
Compressibility.

The question was about fluffiness, not spam.
