Tomorrow is the day to express your creativity, support free speech and win $5,000 in scholarship money through Twitter. December 15 is National Bill of Rights Day, which marks the 220th birthday of the First Amendment.

Here’s how it works:

Beginning at midnight on Dec. 15, students ages 14 to 22 can tweet their support for the First Amendment with the hash tag #freetotweet, which will enter them in the “Free to Tweet” scholarship competition. Students are encouraged to freely express themselves in their entries, which can be posted on any publicly viewable social media platform, including blogs.

The goal is to spread the word that a free press and free speech matter, so even non-student journalists are encouraged to take part.
