Splash! is a yearly academic outreach program that invites middle school and high school students to visit MIT and attend classes created and taught by MIT students and alumni. Splash! is run by MIT's Educational Studies Program, known to most as ESP.

Classes offered over the program's two days present a wide variety of options and are often considered reflective of the MIT culture. Splash! classes are generally two hours long and range from discussions and interactive projects to intense academic seminars. Attendees are encouraged to take as many classes as they would like.
