More spirals? Wormholes? Hoaxes?

After reporting on the Norway spiral earlier this evening, I discovered under-the-radar video that shows a spiral forming over China. It also shows an excitable scientist type guy obviously flummoxed over what it is. Since the video is in Chinese I cannot vouch for its content nor authenticity. But I wonder, are all these spirals failed missiles?

And remember this? I reported on it in October
