So, well before the rockets illuminate the skyline and TV screens across the country, a team of pyrotechnicians spent months testing fireworks in a desert in California.
On the one hand, bringing novelty to fireworks displays can be a challenge: They have long been an Independence Day tradition, an expected explosion of light and color on the night sky that heralds the end of the holiday festivities.
But just because fireworks are de rigueur does not mean they have lost their power to enthrall. Every Fourth of July, people across the United States pause and lift their eyes toward the heavens. They watch for a minute or two or 10 with a kind of public gasp, rapt with attention as streaks and bursts and waterfalls punch through the quiet sky.
