Nerdy-science-geek question: What kind of pressure am I looking for if I want to bust algae cell walls by sending a algae-concentrated liquid through a small aperture? I mean, behind the aperture, size of aperture, etc....knowing that the sudden reduction in pressure *should* bust things up. Any thoughts? Of course, I am wondering about doing this in terms of what I've read, and may experiment with in future, but don't have firsthand knowledge of. Thanks in advance!

Should I eat it filter: Can of Bumblebee whole baby clams. Dumped them into my chowder only to notice that they looked a bit green. Google indicates this might be algae in their tummies? Should I eat them? Chowder is currently simmering, but will be tossed if that is what I need to do.
