Here’s a short video on movement of Protozoa’s present in Rumen fluid, as seen under a Foldscope. Sorry for the bad video quality, tried my best juggling the camera phone, foldscope and trying to keep track of the protozoa which swims quite fast!!. As for the method of I kept a drop of the filtered rumen fluid onto the included coverslip and directly viewed it under the foldscope.
