questions about firecrackers..

tonight i plan on making firecrackers for the first time, and although i know how to make them, i still am a bit unsure of what to expect. first of all, will they stink up my whole house? would it smell like im cooking with weed?

and second of all, can firecrackers be cooled and saved for say tomorrow or sunday? would they still get you high or would you need to reheat them?

thanks for the answers in advance, guys

1) Don't know about stinking up the house. That's always a risk cooking with weed; seal your tinfoil very well to minimize the stank.
2) Yes they can be eaten cold later.
