I can’t help with making fireworks or explosive devices.
Buy legal fireworks only from licensed sellers and follow all local laws.
Read and follow the manufacturer’s instructions exactly.
Use fireworks outdoors in a clear, open area away from people, buildings, and dry vegetation.
Keep water, a hose, or a fire extinguisher nearby.
Light fireworks one at a time and move away immediately.
Never relight a dud; wait, then soak it in water.
Never hold fireworks in your hand while lighting them.
Never modify fireworks or combine them with other materials.
Supervise children closely and keep them away from fireworks.
Dispose of used fireworks by soaking them in water before discarding.
