*Clear* C6-7 motor (link)
Hello All,
Here is an interesting video (see: www.youtube.com/watch?v=_xvVJQSGHts ) of a *clear* Estes C6-7 motor being fired, shown at several frame speeds. The production of the glass tubing-cased transparent motor is also shown. I wonder when Estes will start selling these? :-)

I know he drilled a little to clean the nozzle, but you can see that the thrust vectored back and forth during the burn. I have some still photos that show a D12 vectored considerably more, enough that it helped tip over a nose heavy rocket and cause it to crash.

Neat but needlessly difficult in the execution... Milling off the casing and then machining down the propellant slug to epoxy it inside glass... I guess for purposes of the video of ACTUAL mass produced model rocket propellant it's pretty cool, but if the idea is to just see a model rocket engine burn through a clear casing, this video below does it MUCH easier and safer (using a clear plastic tube)... (from 4:45 onward).

Thank you for posting the video of the "scratch-made" clear-cased motor. Another type of clear motor that I've seen pictures and videos of is the acrylic-fuel hybrid motor, in which the "integral fuel grain/casing" consists of an acrylic cylinder with a void running down its center (these see-through hybrid rocket motors are also sometimes featured in science museums as "hands-on" rocket demonstration exhibits).

If you know anyone who has lymphedema and/or veinous edema in their legs, I discovered an almost embarrassingly-simple solution to the persistent open wounds problem that could help them. For years I had sat and slept (I have to sleep in a recliner chair; I can't sleep on a bed because my back locks up if I try, due to ankylosing spondylitis) with my feet on a box that served as a hassock, but my legs were angled about 30 degrees down from horizontal. Just switching to a taller hassock that keeps my legs almost horizontal resulted in my leg wounds closing within less than three weeks!
