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.
