IRA FLATOW, HOST:
And now for our Video Pick of the Week. Flora's still here and positioned perfectly to take us on a safari.
FLORA LICHTMAN, BYLINE: We're still on safari.
FLATOW: We're still on safari.
LICHTMAN: The safari continues, this time to slightly larger organisms. See if you can see with your naked eye, and maybe in your own backyard. These guys are glow-in-the-dark - I have you already, don't I?
LICHTMAN: Millipedes - which, I didn't know - let me - can I tell you the story of how this came about?
