D12-5 trashes aquarium!
Hello All,
If you were a cracked aquarium, would you rather just be tossed out as trash, or would you rather go out in a blaze of glory? That "privilege"--if one wishes to consider it as such--was conferred upon *this* aquarium (see: www.youtube.com/watch?v=czwBWB5u6Hg ), in which an Estes D12-5 (which, interestingly, was labeled "MODEL ROCKET ENGINE-MOTOR" [the fellow who videoed the underwater firing mistakenly said that it was a booster]) was fired while he recorded the event in slow-motion video (it's presented at actual speed as well), and: He also fired an Estes C6-7 motor in a transparent vacuum chamber (see: www.youtube.com/watch?v=GxBRQXxBRic ). He mistakenly thought that the C6-7 normally burns (produces thrust, that is) for about 8 seconds, and he noted that "It burned in only about a second in the vacuum" (which is roughly the C6-7's normal thrust duration, of course, with the other 7+ seconds of burning involving the smoke-producing delay charge and the ejection charge). In addition: He also made and fired a transparent model rocket motor (see: www.youtube.com/watch?v=_xvVJQSGHts ), which he produced by milling the rolled paper casing off the nozzle/propellant/delay charge/ejection charge of an Estes C6-7, which he cemented inside a glass tube of almost exactly the same internal diameter as the paper casing. Ah, such fun!

..and he said at least a couple of times he did't think it had an ejection charge. With all his cleverness you'd think he could have read what the numbers mean somewhere......
That said, it was quite something to watch.

I prefer the Dorothy Parker version: "You can lead a horticulture but you can't make her think."
