Answer:
Every fourth of July, the people of the United States of America celebrate the Independence Day of their country. This special holiday includes many customs and traditions. On that day, families get together for picnics, parades, fireworks and etc. The people who celebrate the fourth of July wear red, white, and blue due to the color of the flag and wave the American flags. But the best part happens at night. That's when everyone gathers to watch fireworks! The fireworks go boom and sky is lit up with colorful sceneries. Some even get to carry sparklers. All these traditions make Independence Day a very special holiday.
Hope this helps it not too long since I'm not American so I don't have much experience :/
