odor of powder and paper burning
Yep. The red paper rolls with the little powder filled dimples in the center of each segment. They made a somewhat nice boom sound, but better yet gave you the real odor of powder and paper burning-- because that is what actually happened. (Kids actually do need to play with matches and fire btw; otherwise they won't learn what to do with these when they are older.)

These things may sound unimportant to the present day parent, but their absence deprives our kids of very important learning.
Computer games are no substitute for unorganized physical play or for other unstructured self-learning.
