Physiology, gravity, and fluid dynamics all come together in The Other Golden Rule from Science Friday. Learn how videos, data, equations, and fieldwork with creatures great and small helped researchers at Georgia Tech discover that most mammals take around the same amount of time to urinate.

Storytelling, shadows, and 3D viewing come together in this Science Friday report, Dark Art. Biology grad student Tom McDonagh tells of the first balloon trip across the English Channel in 1785, and how he and other puppeteers are telling the story with laser cut puppets and 3D shadows. Yes, 3D shadows.
Of the suit he wore on the moon, Neil Armstrong wrote, “it was tough, reliable, and almost cuddly.” But that cuddly suit, made by the company Playtex, had some stiff competition (literally) from rival rigid, metal designs. This video features archival NASA footage of mobility tests for several spacesuit prototypes. Music is from the band One Ring Zero’s album “Planets”.
Hey kids! Go rest your hands on a speaker playing loud music. Feel the sound vibrations? Good. Now you might want to adjust your volume for this one.
Sound frequencies produce a variety of increasingly intricate resonance patterns. And if you sprinkle sand or salt on a metal plate that is vibrating from these sound frequencies, you can see the patterns.
Did I explain that correctly? If not, Science Friday has a great video that explains it super clearly. Highly recommended.
Food coloring tests and a robot water strider? We love @SciFri!
Water striders don’t really stride, they row on the water. But their legs are spindly and don’t seem good for paddling. To find out exactly how water striders propel themselves mechanical engineer David Hu, of Georgia Tech, filmed them rowing on food coloring and built his own robostrider.
