Houdini Birds and the Space Dagger

Researchers in Australia have been trying to track magpies using tiny, featherweight transmitters, but the birds have banded together to escape the magnetic backpacks that house the signal. This kind of cooperation has never been observed among this species and it raises a whole bunch of new questions. Anthony and Jeff take a look at those wily birds, and what this could mean for their incessant pranks. Then, new analysis of a dagger found in King Tut's tomb reveal that it is made out of iron from a meteorite. Jeff and Anthony step through the incredible process used to make that discovery.
