grapefruit

I did Fine Needle Aspiration on a grapefruit today! FNA is a process where you extract cells from a tumor or mass with a needle for biopsy.

What you do is insert needle into grapefruit, then saw the needle up and down to cut up "tissue", and draw up juice. Then you let a drop of the juice fall onto a microscope slide, and smear the drop with another slide for reading. Voila! Somewhat painful for the grapefruit, though.
