The world's smallest fireworks

It's amazing what you find on ebay... I couldn't resist buying these tiny 1/12 scale dummy replicas of Standard and Pains fireworks. They are intended for a doll's house; here is a link to the seller's shop:

Has anyone managed to create small working fireworks? I'd love to see a nano-fountain, roman candle, etc. I did a search and came across an article on visco powered rockets:

only thing ive ever seen that small is a microgram cracker !
I'd LOVE to see working versions....even if theyre very very simple !

For this project to work I am going to have to seriously optimize my BP and fountain mix to leave no slag which may block such a small choke causing a mini CATO or burn through.

The first rocket was constructed with 7 x 1cm pieces of Chinese paper-fuse, rolled up in a 1cm x 50mm long sticky strip of a post it note (I expect masking tape would work fine here). One of the pieces of paper fuse was cut longer to provide the ignition. The outer decorative paper was a geometric "star" pattern copied from old Chinese paper, and printed on laserjet. (I have templates of this if anyone would find useful). The engine was sellotaped to a stick, made from a bamboo kebab skewer. The fibrous nature of bamboo means a single skewer can be split into several very thin, straight and lightweight sticks.
The little rockets reach an altitude of ~1 metre! There was also a single star payload on the first one, which worked ok, but was still burning when it fell to the ground. Perhaps a micro-titanium salute would be better? The second and third launches are the same design but the propellant is a single 1cm piece of silver "flying fish" visco. It gives an inpressive amount of thrust and a prety trail of sparks!
The third launch was filmed indoors using the high speed function of a HD camera at 60 frames per second. As a professional scientist and part-time film producer I have access to some ultra high speed cameras so I hope to make more movies in future. I will be thinking about designs for a micro-mine-of-serpents and micro-catherine wheels (coiled visco alone might work for wheels).
I am looking forward to seeing those micro-fountains, thanks for all your input on this topic and take care!
