It has lasers!
(insert awesome laser picture here)
And it shoots lasers at cells!
Cells
and lasers are cool!
Therefore, flow cytometry is double-cool! Maybe even Gigacool!
And, furthermore, that the physics of how it works and its optics aren't too convoluted to understand! Woo! And it calls groups of different cells pots! Pots! How absurd is that? Would you like a pot of cells? Why yes, sir, thank you very much, but may I have some PE-A and CD3 with them? Ah yes, very tasty. Lasers!
