Some of the strangest types of rocket nozzles(Toroidal Aerospike, Linear Aerospike, Expansion Deflection Nozzle, and Bell Nozzle) and how I designed, and tried to optimize them. Each nozzle is 3D printed in either PLA or PETG and powered by a 2 liter bottle whoosh rocket.

The Rockets produce a lot of heat and pressure, only adults who are willing to accept responsibility for their own safety should experiment with things like these whoosh rockets.
