Okay so my Biology class were experimenting on the reproduction process of Purple Sea Urchins the other day. It was very interesting . My teacher used a needle to inject a salt based substance into the Urchin to secrete sperm cells from the males, and the same process to secrete eggs from the females . Then he used a sort of suction type thingy to place both the sperm and eggs under a microscope for us to watch the fertilization begin. I mean, it's one thing when somebody just TELLS you what happens, and how it happens , but its a whole nother ball game to actually watch it . Pretty fascinating stuff . 
Too bad Mr. Rosen & Mr. Parker didn't inform us that they wouldn't survive , until we where done with the experiement :(
