A Model Rocket Engine that you can See Through, see inside, how it works and burns through t' various stages, me bucko, I filmed it in 4k slow motion and ultra slow motion so we can see exactly how t' fuel burns and produces thrust inside t' solid rocket booster. Avast! This transparent model rocket engine shows you what's goin' on inside that little engine when it launches. This is very similar t' how a solid rocket booster works on various other rockets as well.
