What actions did Americans take to show their patriotism after Pearl Harbor?

The Japanese attack on Pearl Harbor in 1941 provided the catalyst for a huge upsurge of patriotism in the United States. It's no exaggeration to say that the attack generated a sense of national unity unprecedented in American history. Millions of Americans came together for a common cause, the cause of defeating Japan. Political partisanship was suspended with all but one member of Congress voting for war with Japan the day after Pearl Harbor. Even the isolationist America First Committee dissolved itself, recognizing that American interests had been directly attacked and that there needed to be a robust response from the United States.
On the home front, hundreds of thousands of men rushed to enlist in the armed forces. Before Pearl Harbor, most of the services had had considerable trouble getting men to sign up. But all that changed after that fateful day in December, 1941. As well as signing up to fight, millions of Americans expressed their intense patriotism in other ways. People formed themselves into civil defense units; there were scrap metal drives to provide raw materials for the American defense industry. People also bought up war bonds, a hugely popular means of helping to fund the war effort.
