After making FIRECRACKERS, can I eat them days later?

Thinking of making them tonight but worried if theyll be good 3, 4 or 5 days down the road. Will they still be Potent? Do I have to eat them right away? Should I store them any place special? etc. etc. Is there anything I should know about making them tonight and eating them later?

Thanks

Well... if you prepare them properly and they work fine, you can store them and they wont lose their potency.

ive saved mine for a few days before and they worked out fine
