アメリカ独立記念日

Today is ７月４日 (July 4). 「アメリカ独立記念日」 (American Independence Day).

I don’t usually do anything special on this day. Although there are many 花火大会 (fireworks shows) in Japan during the summer, they don’t usually start until late July or early August.

Watching fireworks is a “Fourth Of July” tradition in America, but I don’t live in America.
(It’s possible that the U.S. military bases in Japan will have a fireworks show this evening. I’m not sure. I don’t live near any U.S. military base anyways).

But anyways, in honor of the 234th anniversary of America’s independence from England, I am writing a list of some of American inventions that have changed the world (in most cases, for the better).

So, according to the U.S. Patent Office, this is a list of some of the numerous things that have been invented in America:
