Obama shoots marshmallow through State Dining Room at science fair

President uses boy's compressor to launch the projectile at science fair.

President Obama spent some of his Tuesday morning touring the White House science fair, where he was intrigued by one Phoenix boy's creation.

According to the pool report, Obama "got excited" when he saw a marshmallow launcher made by 14-year-old Joey Hudy and asked if to see it in action.

"The Secret Service is going to be mad at me about this," the president said before pumping the compressor and watching a marshmallow shoot across the State Dining Room.
