Vortex Cannon
- frossie 16y ago... and then the third little big actually put some mortar between his bricks...

- frossie 16y agoIs there a technical term to describe typos that form legitimate words and therefore don't get flagged by a spelling checker?
- dpik 16y agotyro ?
- vsthesquares 16y agoType II error? ß-error?
- util 16y agoMaybe a "typo II error"? :-)
- po 16y agoI don't think there is. I suggest: typhous
- Daniel_Newby 16y agoMisspelling.
- RiderOfGiraffes 16y agoSo, he's firing vortex rings at 200mph from an acetylene powered cannon, and you complain that he didn't use mortar on the construction to demonstrate the impact? Interesting ...

- shpxnvz 16y agohe's firing vortex rings at 200mph from an acetylene powered cannon Which, while sounding impressive, apparently is only powerful enough to knock down things that are equally vulnerable to being bumped into by a toddler. Perhaps it's just that the reaction of the host in that video seems a bit out of proportion to the actual accomplishment?
- RiderOfGiraffes 16y agoThank you - I've learned something. I honestly hadn't believed that someone in HN could fail to appreciate what's really going on here, but you've convinced me that some people just don't find it impressive. Having built air-bazookas of various sizes as an exercise in hands-on science at kids' roadshows and exhibits, they (the kids) are always impressed by the targeting, impact, effect, and sheer unexpectedness of the vortex effect. Maybe I've become overly infused with enthusiasm for these sorts of things by the naive excitement that children get from this sort of thing. Maybe it's just so much better doing yourself for real, rather than just watching it on a video. I know a lot of experiments and demonstrations that are truly impressive and awe-inspiring in real-life, but cause very little reaction when viewed on video. The video experience immediately removes you from the personal experience. To better help me understand your mindset I looked at your profile. There wasn't any information about you, just the two links. I was interested to see that the first was about a web monitoring service, and even more interested to see the result of visiting the second: There has been an error processing your request. SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES) Trace: ... <snip> ... I would've sent that to you personally rather than posting it here, but, as I say, your profile has no contact details. Just thought you'd like to know.
- donaq 16y agoIt's some way off from being a weapon, I think. The bricks didn't so much blow off as they fell off (from being blown off balance). Ok, I did not say that very clearly. Still, awesome experiment.
- Malic 16y agoI want one. Much like a Bugatti Veyron, I have no idea when I would have the opportunity to really use it or where I would safely store it but I want one nevertheless.
- ComSubVie 16y agoI think it is to big to mount it on a Bugatti Veyron, but it would be nice (would the resulting Vortex Ring be faster by the speed of the car, or would the car drive into the ring, if it is fast enough?).
