<p>Most seventh grade science fair projects don’t involve heavy artillery, but one student from Sweet Home, Oregon, included a fully-functioning cannon to complete her assignment.</p><p>Emma McCubbins decided she wanted to shoot bowling balls out of her great-grandfather’s old cannon, then mathematically determined how high each of them went. She did this with the help of her dad Gabriel, using the in-flight barrel time and distance traveled.</p><p>They strapped a GoPro onto the bowling balls in order to help with the visual presentation of Emma’s projects, resulting in some pretty cool footage.</p><p>The video had over 280,000 views at the time of writing.
