You may wonder how to view a stomata under a microscope where the leaves is opaque and will block the light of the microscope. Then normal dissecting microscope can only view up to 80x magnification. Here is the method where you can view the stomata at 400x magnification.
All you need are light microscope, clear nail polish, clear scotch tape and a leaf.
Paint a thin layer of nail polish on the back of the leaf. Wait for about 5 min for it to dry. Then use a clear scotch tape to stick onto the leaf where the nail polish is. Then pull up the scotch tape to allow the nail polish imprint to stick onto the scotch tape. Then stick the scotch tape onto a glass slide and happy viewing your stomata imprint.
Here are the imprint I made.
