Eutectic sugar propellant with phenolphthalein and cellulose nitrate coating

Experiment performed as following:

- 6.5g KNO₃ and 3.5g LiNO₃ mixed in a beaker

- 20min heated in baking oven at 160°C under air circulation mode

- 3.5g fine powdered sucrose and 1g phenolphthalein added after salt mixture got liquid, stirred till it got a homogenous white paste

- Poured on a coated baking paper, coated with nitro cellulose lacquer, cooled down to room temperature, ignited

Result: Less residue due to phenolphthalein additive, no hygroscopic effects due to nitro cellulose lacquer coating.
