😏IF those are used to test or calibrate a machine. How can they 'contaminate' them if covid-19 still is not isolated in its entirety?

What are those tests being contaminated with?
What is actually being tested for?

A doctor and scientist did a video showing what is on the tests. They first began with a simple cotton swap to show what cotton looks like. The actual 3 tests showed the substance on the tips was not cotton at all and they were not able to identify what it was. They then went to the first test which was sealed initially and it tested positive for the virus & put under a magnifying microscope to show oddities on the tip. The 2nd test they showed what appears to be the actual vaccination as well as some sort of magnetization through some sort of smart dust and you clearly see it. The 3rd one contained what was Morganella threads which looked like wires. I learned of Morganella 15 years ago from states in the midwest who were having ulcer like sores and threads coming out of the sores and the doctors said they were mentallly unstable. Those threads are actually live worms & you could see them fight one another under the scope. All 3 tests are pushed right up against the brain area.
