How long do fireworks last?
Fireworks have an extremely long shelf-life so long as they are kept dry. For ideal storage, keep your fireworks in a non-humid environment with a fairly consistent temperature, stored in a cardboard box. Do not store fireworks in a sealed plastic cooler, tub, or tupperware container: these materials prevent air circulation and may cause condensation. This way, your leftover fireworks from Victoria Day, Canada Day, Labour Day or New Year’s won’t be wasted!
