Write the procedure to observe human cheek cell

To observe the cheek cell,

Take a tooth pick use its blunt side to scrap inside the mouth. You will see some deposition on the blunt side of tooth pick, make a smear on the clean slide in the center using that tooth pick. Add a drop of methylene blue solution and place a coverslip, make sure that bubbles are avoided i.e. coverslip should be placed in the inclined manner.  Remove the excess solution and observe it under the microscope first under 4X and then under 10X.

Observation:  

The cells observed are squamous epithelial cells. The small blue dots seen inside will be the bacteria from our teeth and mouth.

I’m not really sure
