TUCSON, Ariz. -- Catapults and pumpkins made for an interesting show Sunday on the U of A mall. 

Local middle school and high school students built their own apparatuses and hurled pumpkins as part of a physics lesson.

"It's distance and accuracy.  So, first it's like how close can they get to the 100 meters and then can they knock down the wall," said Dolly Spalding from Physics Factory.  "They are learning a lot about engineering and math and having fun with science."

The kids had a lot of spectators, including Raytheon engineers who were actually judging the event.
