In a mass act of generosity, stars like Gwyneth Paltrow, Serena Williams, Anna Kendrick and Ashton Kutcher are ensuring that American schoolchildren from cities important to them have the #BestSchoolDay ever by flash-funding classrooms in need.
On Tuesday, the stars will be donating well over $12 million in total to DonorsChoose.org, a site where teachers post classroom project requests ranging from art supplies to new computers to robotics kits.
Hoping to prove the "best school day" ever really does exist, the altruistic celebs have pre-recorded video of themselves describing their own favorite school memories.
