Have you seen the new and improved Catherine-wheel ?

New and improved Catherine-wheel ...

I think that it was posted in the YouTube classics thread several months ago. Pretty impressive though.

This is fake. For one, small rockets which are powerful enough to lift the weight of something that large don't burn for more then 5-10 seconds. Second, for that thing to be stable, it'd require the rockets to be carefully synchronized at launch and during flight - lighting a bunch of wicks with large sticks doesn't cut it. Third, it just looks fake - the motion and smoke trail are far too regular and symmetric.

Is it really using short burn rockets to lift it or is it using long burn fire works to spin a propeller device that does the lifting. Regardless it was very impressive. : )

If it is a fake it's very good : CGI smoke is difficult. As for weight , it's just a framework, not a solid disk.

Like a flywheel , the moment of inertia would smooth out any unsynchronised / asymmetrical rockets.
and gyroscopic action would keep the ring horizontal.

The ring does have blades in it , but they are not radial ...

I have a feeling that some of those people around it were holding it steady until the gyroscopic action was sufficient. Then they ran link He11.

Correction it appears to be sitting within a circular structure that kept it stabilized until the gyroscopic action was sufficient. On full screen it looks even more impressive.
