Linkhorne Middle School Students Launch Water Jugs

Lynchburg, VA - The students at Linkhorne Middle School just finished reading King Arthur and His Knights of the Round Table.

As a reward, they got to launch water jugs and bowling balls with a trebuchet, the weapon before the days of tanks and cannons.

It can throw objects 450 feet or more. Boy Scouts working on their merit badge built the machine years ago.

Now it's around the area to demonstrate engineering principles.
