I was wondering if the lack of labeling bothered anyone else. 

I agree this isn't a chemistry demo.  It's a gee-wiz/magic show.

I don't think it's chemistry when an unidentified liquid is mixed with something off screen to produce an unexplained pop. Perhaps it can fall into the realm of alchemy, but there's nothing scientific about this demonstration.
