Soldering on the International Space Station

Astronaut Mike Fincke, using a Weller soldering iron, found that a drop of rosin will spin around molten solder in a weightless environment.  Courtesy of NASA.

2 - Why was the smoke rising? or flying away from the soldering iron? if there is no gravity to make the heat rise. why did the smoke just not pool around the solder? (Comment this)

3 - Curt, I believe it would be reasoned that where there is heat, there is expansion. One of those pesky laws of thermodynamics that Boyle contributed to… The surface of the board acts as a reflector and the gas flows toward low pressure. (Comment this)

4 - If you look at the smoke very little is going straight up. It's probably going in the direction where the ventilation fan is located :)

Also note that the term "going up" makes no sense, as the camera and equipment could be oriented in any direction "up there". (Comment this)
