Sound Shells (Noise Makers) are small spiked items which produce a loud detonation and sometimes have an added effect like crackling, whistling or bright flash. These are the loudest fireworks available in Canada.
One or more Sound Shells can be ignited at the start of a fireworks display as a call to spectators, letting them know the show is about to begin. Use intermitently, throughout the display for added noise, or ignite at the same time as an item that is more visual in nature. There are several different Noise makers with varying small visual effects to spread throughout the fireworks display.
