Fireworks! Happy Independence Day 2025!

Fireworks, right up there with flags and apple pie as an iconic image of July 4th celebrations! Yonkers Public Library is no exception as it brings you Fireworks in a Jar (bowl) on June 28th during the STREAM Storytime at Crestwood Library! Each child will have the chance to see this colorful chemical reaction! (Don’t worry, another version will happen on Saturday, July 5’s STREAM Storytime!)

Now, to see Fireworks in the sky! Yonkersians and others are looking forward to 4th of July Fireworks at the Waterfront | Yonkers, NY! All along the Waterway Walk you can view fireworks on the river and there’s music too!

Westchester magazine has put together this list of events, Where to Watch Fourth of July Fireworks in Westchester County.

Fireworks were first introduced in China in the first century BC when, the story goes, someone threw a piece of bamboo into a fire and it exploded because of the air pockets found in this plant. Travelers in China started carrying bamboo to light it and scare off wild animals. In the 9th century BC, gunpowder was invented and Chinese fabricators began filling the hollow bamboo with it. Fireworks continued to grow in popularity to celebrate special events like weddings. It was John Adams who suggested that Independence Day be celebrated with pomp and parade and grand illuminations! By the 19th century, chemicals were added to make brilliant colors. Now, the highly advanced pyrotechnic shows are a bit different than the bamboo, but the fireworks are still often made by hand. (Thanks to NPR for this information, The history of fireworks, from ancient China to Revolutionary America : NPR.)
