I wouldn't want to put my head under but would like
to try it in a sensory deprivation chamber. A black
sea. |

Need a dust mask or better, to protect the lungs from this. |

No. Fluid dynamics indicates that the person will
immediately sink to the bottom as they will exhibit
dynamic density greater than air while the metal dust
exhibited only partial fluid behavior. |

I'm not so convinced...
First of all, the video is showing partial submergence.
That is expected, because, with possible exception of
one guy, no one can walk on fluid without displacing an
equal mass.
Secondly, the only references I can find, on fluid
dynamics in fluid beds, refers to small particles which
behave differently.
I still think that large objects will react according to
equivalent bulk density, unless someone can point out
any strange other behaviour. |
