A rocket that launches vertically, horizontally, or sometimes just rolls around on the ground in a delightful spiral of sparks.
Is it a dud, or will it go off in 5 seconds? Or 5 minutes? Nobody knows! Keeps your guests on their toes.
A beautiful shower of sparks that has a tendency to wander away from its designated safe zone.
Looks like it's going to be a huge explosion, but then quietly fizzles out with a sad little puff of smoke. (Our best-seller for ironic celebrations).
