8th Grader Demonstrates Marshmallow Air Cannon for President Obama

At the White House Science Fair, 8th grader Joey demonstrated his homebuilt air cannon for President Obama by launching a marshmallow across the State Dining Room. As the student pumped air into the cannon, the president joked “the Secret Service isn’t happy about this.” Then the president took a turn pumping air into the cannon.
