Don't Throw Rocks! Talk About Bad Luck

Post by Mitch640 »

I recorded this video in Phase Contrast, of a ciliate on a slide and what looks like an inert speck of rock or other sediment that shoots into the ciliate, killing it, then shoots out of it's side and out of the frame.

I have never seen anything like it or have any kind of explanation for it, other than that the water floating the coverslip had evaporated and the weight of the settling coverslip shot the rock out at an unfortunate direction for the ciliate.

Thanks Curt. Video is my favorite past time. I intend to do many more. Right now, I am getting a feel for what phase contrast can do and what it does it best on.

Unfortunately, the guy I bought these from did not have a 10x PH1. 10x seems to be the out front leader in what lens to use for video. Unless you have immobile subjects, it's just too hard to keep the movers in the frame. Well, except for amoebas. :)

Mitch,

Nice video, you were lucky to be filming it.

Thanks Rogelio. I use to work in heavy construction, steel foundries and shipyards and building of watertowers. I have seen wedges and hammers get the pinch and go shooting off just like that piece of rock in miniature. I've even been hit with a small piece of steel that chipped off a caterpillar tread. It's called spalling.

To see this makes me roll my eyes that I was lucky enough to never see it happen to someone I know.
