What's in the vials? Pfizer Cominarty under the microscope (REVISED).

On 25 October 2022, Dr David Nixon recorded microscopy video of a sample of Pfizer Cominarty - Pfizer's covid-19 product - which had been prepared nearly 12 weeks earlier, on 4 August 2022, and stored in a slide cabinet with no cover slip. Instead of the dried up crystalline mass which I think we would expect to see, there seem to be objects moving around in a fluid medium. According to Pfizer and government information, the product consists of mRNA inside lipid nanoparticles suspended in an aqueous solution. So why has it not dried up?
I also present evidence that the medium seems to show some characteristics of an elastic skin or membrane, while at the same time sometimes flowing like a liquid. I suggest tentatively that it may be a hydrogel.
