I try and burn a Model rocket engine submerged in liquid nitrogen t' see what's goin' t' happen, matey, also filmin' with a 4k high speed ( slow motion ) camera it should yield some interestin' results, Model rockets are cool and in this case very cool, ya bilge rat, -320 °F cool, How does this work ?, lets find out. Well, blow me down! I build a couple different rigs t' see if I can get a clear view o' t' engine for our high speed camera and see what t' high speed footage reveals.
