In some ways, Independence Day fireworks shows are one of the last collective events in our highly fragmented digital society. Inherently three-dimensional experiences that are often poorly rendered on two-dimensional screens, they demand — loudly and vividly — our time and attention.

Of course, in these increasingly polarized times, fireworks also have the power to divide. Among the critics: eco-friendly researchers who suggest that fireworks may be bad for the environment; audiologists who warn that the explosions can lead to hearing damage; and pet owners who say the noise causes both them and their animals anxiety.
