A trivial device, a 1/4" lance about 6" long with a drumhead of pasted kitchen paper then funnel and wire charged with a simple flitter (similar to Oglesby delayless glitter) composition:
6 Potassium Nitrate
2 Sulfur
1 Charcoal
1 Aluminium (atomised, 16u)
The composition was simply screened together and contained quite granular particles of Potassium Nitrate and garden Sulfur. The tube was closed at the handle-end with some paper wadding stuffed tightly against the powder charge.
Calm and simple effect.
Somewhat like a morning glory, less spectacular, but more interesting in many ways. For such a simple composition, with a simple preperation the device worked quite nicely, a perfect belated birthday present for myself.
