I was thinking about bacteria and they are too small to be seen by the naked eye. Then I wondered what it would be like if you got all the bacteria in the world and put them together in one big pile! Tried a few google searches but no luck. Then I thought you guys are likely to have a good shot at answering this.
How big would the pile be? The size of a tv, a large room. an olympic sized swimming pool?
And what would it look like? A big pool of brown goop? Extremely fine green dust?
I seem to remember in biology class that we grew something in a petri dish. It was white (I think), is that mostly bacteria or would it have been spores??
