This one is more like an actual fountain.
The same KN/Sucrose/Lampblack mixture that coated the paper in the first device was found to be a poor rocket propellant, so I rammed all I had left into another thin kraft paper tube.
The bottom of the tube was sealed with paper wadding and hot-melt glue. The top fused with a meal-IO fuse and some wadding added to protect the composition.
The video doesn't do it justice.
Even without a choke of any kind, and using a case that burnt away, like a lance, the effect was quite pleasing. The lampblack gave nice sparks and the hint of potassium purple to the otherwise orange-white flame was quite attractive.
There was nothing left to take home and study, even the wadding burnt away.
