The phrase "disposable microscope" sounds rather strange. However, from now on such a device exists in nature. Depending on the level of illumination, the “microscope” (seemingly just a thin plate) allows you to magnify objects by 500, and even 1000 times! A good toy for kids - though foreign ones. A package of 5 plates costing $ 89 is not affordable for every parent.
With the help of magnifying plates you can examine the structure of human hair, plant cells, various microscopic animals and even blood components - in general, who is interested. Our foreign colleagues, for example, did not come up with anything better than how to use a novelty ... to count the number of sperm - we hope they are not going to do this procedure in crowded places. :) ')
