It certainly did the trick - sort of - in demonstrating the idea of a 'meme', as the Twitter trend showed. But did it lead to a better understanding of science by the public? I imagine not: most who viewed it would be mystified rather than enlightened. Those who weren't too busy wiping away the tears of laughter, of course.
This, in turn, raises the larger question of the remit of those working on advancing the public understanding of science. Should they be saying 'yes' to any opportunity to engage with the public? Is being out there, being seen by the public, enough in itself, or should they choose their engagement carefully?
You won't be surprised that I think the latter. I believe there's a danger, with these kind of events, of public intolerance with both boffins and conceptual artists becoming conflated. And that, ultimately, will be to the detriment of both.
