Screw the F-35 and the Navy's railguns! This air cannon that can shoot marshmallows as far as 23m is what the Pentagon means. Or at least, that's what Obama needs, perhaps his most powerful weapon to fight Romney.
The President meets an 8th grader named Joey from Phoenix, AZ at the White House Science Fair and the two launch a marshmallow across the State Dining Room of the White House with Joey's science project — an air cannon.
He didn't only "meet" him, as the White House official YouTube channel puts it. He was excited to try it!
Joey: "I use it to shoot marshmallows."
Obama: "Shoo — shooting mars*CAN WE DEMONSTRATE? [...] Would it hit the wall? Would it stick? Let's try it. Let's try it up!"
Then, after some joking telling people to back off so they don't get hurt, he seems genuinely excited:
Obama: "[laughs] This is great! [...] Secret service isn't happy about this."
Then he pumps air into it, the kid launches it and Obama screams "WOW! OOOWOW!"
Yes, I love to see the most powerful man in the world shooting a marshmallow across the White House like a little kid.
