Seems microscopes are pretty much way over hyped.(watching too many science movies)
I'll just stick to watching coins and rocks.
One of my major interests is too look at crystals of different substances (e.g. vitamins), normally using crossed polaroid filters.
Sure you can't see the atoms or the molecules but you can see a lot very interesting things like the huge variety of crystaline forms and amazing colours.
You can also watch the crystals grow, which you know, even if you can't see, is due to the molecules coming out of solutions and adhering to the surfaces of the molecules.
Its really fun and quite addictive.
Occationally you can see the effects of molecules. Brownian motion can be viewed in various ways (try googling, searching this forum).
I have sometimes seen this with very small crystals. Its amazing.
I saw the faces fo the crystals turning and giggling around due collisions with the solution's molecules.
