What: Throwing raw eggs off a five-story building doesn't always mean a messy splatter of yolks and egg whites. For the past 17 years, a UC Davis student engineering organization, the Materials Society, has sponsored an egg-drop contest to land eggs safely. The event attracts hundreds of community participants. Small, light vehicles designed to protect fragile shells, the delivery-devices are also judged on design (creativity and materials) and weight (lighter the better). When: Friday, Feb. 23, beginning at 9 a.m. Where: UC Davis Physics/Geology Building, front steps Visuals: From the ground and the roof, cameras can capture the successful and unsuccessful attempts to hit the target. In previous years, eggs have been tucked in foam footballs, padded boxes, parachutes, a rubber chicken and even a rag doll. Parking From Interstate 80 take the UC Davis exit. Turn north on Old and Directions: Davis Road. At stop sign, go straight and continue straight to the Hog Barn. Park against the north or south fence of the Hog Barn.
