That mesoscope thing is expensive -- $500???? Anyone have any experience with a jeweler's loupe? I heard of someone using that.
I tried using a magnifying glass on a tweezer / magnifying glass combo set but it was too small -- I need a bigger one -- but yeah the tiny stuff is incredibly fascinating.
I had this one critter that was really tiny but it looked like a little bullwhip that would just rise up in the water and whirl itself around in figure eights -- never figured out what it was. It was about a millimeter in length, and half of it was a straight rod, and half was a "tail", and it would just whirl around and around and lift itself up 5-6 inches in the water, then rest for a few seconds, and whirl again. I saw it every time I turned off the flow and added DT's. It was pretty neat looking but I have no idea what it was.
