Not that I disagree, precisely, but I’m not sure you can use the Comed-Tea thing as evidence that it’s possible to analyze how magical objects work: Quirrell and Dumbledore both seemed taken by surprise by the actual effect, after all. The charm(s) they used seem more likely to be poison/biologically-interactive-potion detectors.
Or maybe they both decided to fake being caught off guard. That seems like Dumbledore’s style, anyway.

So was Draco, who had been told the effect; unlike Harry, he probably didn’t doubt that the thing worked, he probably just thought that it’d be lame.
