It's being called "flash funding" for school projects across the country, including in Connecticut.
More than 50 athletes, actors, company founders and others announced that they will fund classroom projects on the website DonorsChoose.org.
The site uses crowdfunding to help schools around the U.S.
In Connecticut, 388 teachers who requested support through the site learned on Thursday that their funding will be granted. Roughly 500 projects across the state will be funded at 188 public schools.
The website said about 40,000 students will benefit from the projects.
"We all remember special days at school, whether it was going on a field trip, doing a science experiment, or performing in a school play," said Charles Best, founder and CEO of DonorsChoose.org. "Teachers have a hard time providing these experiences when their classrooms lack resources and when they have to go into their own pockets to buy school supplies. We're so grateful to the people who've kicked off this philanthropic flashmob, and hope that everyone - no matter the size of their wallet - will join this act of mass generosity by supporting a classroom project and committing to make every day a #BestSchoolDay."
Late Show host Stephen Colbert, who with the help of the site and Best, funded every classroom project in his home state of South Carolina.
Colbert said he's a board member for DonorsChoose.org.
"It's my favorite charity because teachers in classroom all around the country can put up any project they want to teach their children or help their kids with that they don't have the funds for," he said on CBS This Morning.
Since Colbert's donation, people like Samuel L. Jackson, Seth Rogen and Dwight Howard have collectively donated more than $14 million to nearly 12,000 projects. The money is going towards books, art supplies, science equipment and other things.
The celebrities announced their intentions to fund the projects on social media with the hashtag #BestSchoolDay.
