I remember looking at Brownian motion in 'science' in first year at the big school. It was a container of waterand some stuff with a light shining into it and things seem pretty random. When I got to sixth year physics, the teacher was setting up the experiment for the 1st year people and said that if the light wasn't there, nothing would happen and this wasn't even really Brownian motion.
Where in all that's holy did Neil get this question from!? 
I'm starting to think he just has a template and fills in a few boxes.

What's wrong with what I think is a particularly legitimate question for a FRiday night !?I'm not saying there's anything wrong with it. But as far as I was aware, you thought bacteria was a type of camel!Ah... maybe that's what the question really is - "Do camels display Brownian motion?" I've just had a silly thought - Brown Ian motion - Mr Beale walking around Albert Square after returning from a holiday in The Canary Islands! 
Hi,I believe that turnipsock reply is not really correct. Brownian Motion is an effect from the enviroment. Imagine particles or bacteria small bigger or small than the other molecules in the solution. They will collide to each other and therefore some thermal energy will arise from the contacts. The thermal fluctiation is Brownia Motion. Please read Howard Berg (Random Walks in Biology) if you want to know more about Browniam motion and other aspects of micron/nano size organisms.
