I looked at my fingernail before putting in the microscope, and i noticed that it was just made up of one single layer, it was actually made of of much more. It actually broke apart into two separate “fingernails”. Then I put it under the microscope and saw all the thin layers at the part where it broke off. I could also see so many little dimples on it that I could not feel. It was very interesting because I thought it would look more smooth, but it did not.
