Build your own Black Hole Machine Picture 1 :- general arrangement of Black Hole Chamber. http://i1235.photobucket.com/albums/ff428/codex34/BHM/chamber.jpg Note: Neutrally buoyant plastic dust should be added to both fluids, to aid viewing of the turbulence generated. Picture 2 :- General arrangement of Black Hole Seed. http://i1235.photobucket.com/albums/ff428/codex34/BHM/seed.jpg Note: Inlet and outlet porting shown is exaggerated to aid visualization. Special Note: In order to distinguish between the turbulence generated by the chamber and that generated by the seed, the porting must be slight but not insignificant, the aim is to generate a similar turbulence to that of an unbound fluid. Other experiments: Replace the Black Hole Seed with 1)a sphere 2)a cylinder 3)a Black Hole Seed without porting. Note: These seeds will require a higher rate of rotation than the original seed.
