Those of you with TV licenses might have seen this last night.
I did and it was a relatively interesting science program which the BBC seem to be pushing as the next Tomorrows World (The Day After Tomorrow's World if you like). Anyway, apart from the ham-fisted presentation there was some good fun SCIENCE in there, not least of which was the 'supersonic vortex cannon'. Now although they say in the piece that the vortex is travelling at 200MPH, or approximately mach 0.3 and therfore distinctly SUBsonic, the final contraption was properly incredible.
Then this afternoon in a fit of boredom I decided to go on the website, and found a surprisingly mature video on the genesis of the 'supersonic' vortex cannon - worth checking out for anyone interested in crazy science.

ReplyDeleteI am enjoying the picture though and may summon enough energy to click on the actual link one day.
Also, I was wondering, why does noone ever embed the videos instead of linking?
I considered it for this one then couldn't work out how to do it, plus it's BBC iplayer which I assume you can't embed.
