What a flame looks like in microgravity
|

Flames look a little different in space. On Earth, gravity causes a candle flame to be teardrop-shaped, and carries soot to the flame's tip, making it yellow. In microgravity, where these forces are absent, the flame is spherical, soot-free, and blue.

The vortex is a spherical field of force, or a magnetic disturbance. The vortex is 165 feet in diameter and sits half way above ground and half below. The disturbance, or vortex causes unexplainable changes in perception, causing naturally occurring visual and perceptual phenomena that has been caught on film many times. Within the spherical distortion, people stand at an angle. The disturbance alters your relative gravity, causing you to stand at an angle of varying degrees. It is not possible for someone to stand vertical inside the vortex. It will also make someone who is walking away, seem taller, or shorter depending on where you stand. Balls roll uphill, brooms stand straight up and down on their own, and chairs appear to be held up b ...
