As a kid, I remember the lead-up to Halloween was often weeks of planning and covertly lighting off firecrackers. The firecracker part is self-explanatory, with the possible exception of bottle rockets -- single stage; three stage rockets are inferior -- that are akin to Silly Putty in the many different uses we came up with, which mostly revolved around firing them out of metal tubes.
But the planning...
That always seemed to me as "carefully considered" like some kind of complicated math problem. We'd consider the best route through the neighbourhood to take, cutting across lawns when needed, take into account what houses gave away full size chocolate bars last year, then timing it out because after a couple hours people took in their jack-o'-lanterns and turned off their lights. Planning the route was key!
