plz tell me effect of humidity on mechanical properties of solid rocket motor It makes it wet and gooey. I will allow others to expand on that (or while thinking about that).

Gawd, I love technical terms... <g> >I will allow others to expand on that (or while thinking about that). Yeah, the humidity causes them to expand. Also, if the humidity is excessive, or prolonged, the nozzle clay will become... um, well, "poopy"...[1] <vbg> tah [1] Actually the nozzle clay will begin to soften and disintegrate. Friend of mine had this happen with a bunch of motors he stored in his basement. -- Tod A. Hilty Hilty Information Systems "Gentlemen, you can't fight in here. This is the war room."

Depends on the motor type. A typical BP motor with a wound paper casing will swell upon repeated exposure to high humidity levels. I recommend storing BP motors in a humidy-controlled environment. Certain propellents (e.g., sugar rockets) are hygroscopic. They will absorb water vapor from the atmosphere. High humidity levels will exacerbate this condition. Keep all of your motors in a cool, dry place. Keep your beer in a cool, dark place.
