Written by Lewis Busch / Imperial News - Since 1972, students at California Institute of Technology (Caltech) have dropped pumpkins from the top of the nine story Millikan Library. The tradition continued this morning as a large crowd gathered at midnight to witness the annual event. According to school legend, it is said that if your freeze a pumpkin in liquid nitrogen and drop it from the right height, a 'triboluminescent spark' will be produced. The crowd waited with anticipation but it is unknown if anyone saw the legendary spark. (Wikipedia states: "Triboluminescence is an optical phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched or crushed.")
