I want to make smoke to simulate spraying from a model crop duster.
All model and most professional smoke systems use heat from the exhaust to create smoke from oil or from a water-based material (e.g., glycerin-water mixtures). That is probably not practical in this application, as the smoke would need to be piped to the trailing edge of the wing. I have considered using heating coils at the point of generation, but want to find out what other options exist for pure chemical production of smoke.
Here are some additional thoughts:
1) I cannot use any pyrotechnic device (e.g., sulfur methods). They are generally illegal for models.
2) Titanium tetrachloride would work, but produces HCl as a by-product. Not good.
3) Dry flour has been used, but aggregates too much, doesn't persist, and is not too realistic.
Does anyone know of any chemical methods for producing smoke that produce less noxious products than HCl?
Thanks. John
