From Creatures Wiki
This firecracker can be "lit" by a norn or by the hand. After the fuse is lit, it will slowly (and noisily) burn down until the firecracker explodes. Before it explodes it can be put out by a norn or the hand, although it can be re-lit (with a shorter fuse).
Lighting the firecracker will slightly raise fear in the lighting norn and slightly lower its need for pleasure. Upon explosion it will slightly raise fear on all norns within earshot and lower their need for pleasure moderately.
