Science Central's Trebuchet Competition - Teams built a 12 foot tall trebuchet using 300 lbs. to throw a 2 lb. sack of flour, watermelon, and pineapple! A trebuchet is a mid-evil weapon that was used to hurl objects over castle walls. A trebuchet uses a falling counter weight and a sling to throw objects great distances. If you want to build one there are lots of videos and sites on the internet to help you learn how!
