The revelry started weeks ago here with all the mini explosions from firecrackers,M-80's and lord knows what else.It sounds like Beirut or Syria at night!
More at the link. DO NOT use random powder from deconstructed fireworks. Use only the Black powder, lift powder described should make one.

So, What is a Cremora Fireball?
In years past I've heard of accidents at grain silos or flour mills, where clouds of dust have been ignited by a spark resulting in a tragic explosion. A bag of flour is not a fire hazard, but mix it with air and it becomes a highly flammable mixture.
It takes fuel, oxygen and a heat-source to produce a fire. A Cremora fireball is simply a device which projects a powdered fuel up into the air, where it gets mixed with the atmosphere, is ignited by the propellant, which results in a large fireball as the fuel and air burn together.
At some time in years past, an enterprising soul decided to project some Cremora brand coffee-creamer powder up into the air using a black powder propellant, and the Cremora fireball was born. Even though Cremora brand creamer is next to impossible to find nowadays, and other substitutes are used, these fireball pots will forever be referred to as Cremora Pots, or just Cremoras.
The simplest of Cremoras can be made with just a metal can, some black powder, a 4" piece of Visco safety fuse, a disc cut out of a paper napkin, and some flammable powder.
