Dale writes – “On a visit to my parents in Louisville, KY, I visited a regional state competition for the Science Olympiad where my nephew, Chase Carlson, competed and won in bridge building. His entry weighed 11.5 grams and held 32 lbs (just one pound short of the 33 lb maximum) before it broke. You can see him filling the bucket of sand, which is suspended from his trapezoid bridge. Chase will go on to the state competition, held in April, in Western KY. Those winners will go on to the National competition at the University of Indiana in May. I also watched students tossing tennis balls with a trebuchet and flying rubber-band powered airplanes that stayed aloft for a wonderfully long time.”
