This was an awesome project. Firing a plexiglass/ Gaseous Oxygen hybrid rocket motor. The plexiglass is strong enough to hold up to reasonable chamber pressures and at the same time we can see the combustion and surface erosion.
You will see that the nozzle gases are dancing around, this is likely due to the unusual erosion near the nozzle.
i think it melted just a lil bit...
