Marangoni Convection in Space
In this Saturday Morning Science video, astronaut Don Pettit demonstrates Marangoni convection in microgravity using a water film with tracer particles, a soldering iron, and a flashlight. This same effect Keep reading
Microgravity Water Films
In this video astronaut Don Pettit demonstrates some interesting laminar flow effects using a water film in microgravity. By using a film, fluid motion is essentially confined to two dimensions. Keep reading
Fizziness in Space
Removing gravity has interesting effects on fluids. Here an astronaut aboard the ISS demonstrates what happens when Alka-Seltzer is added to water in microgravity.
