AGE EIGHT SEC—B UNIVERSITY DAILY KANSAN, LAWRENCE, KANSAS FRIDAY, APRIL 20, 1951 Misdirected Egg Inspired First Engineering Exposition Bv BEN HOLMAN A University professor was splattered with a rotten egg in 1922 and there's been an Engineering Exposition ever since. The ill-fated professor stepped into the corridor of Green The ill-fated professor stepped into the corridor of Green hall the middle of an engineers' egg bombardment. The previous day, someone had The previous day, someone had spoken into one of the engineering boratories and destroyed the floats or the annual Engineers' Day parade. The engineers suspected their ch-rivals, the law students, and taliated by decorating Green all with over-ripe pullet pellets. As a result of the "battle," Chancellor Lindley ordered the abolishment of Engineers' Day. The next ear P. R. Walk, dean of the school of Engineering, fostered the ea of an exposition to replace that ay. The chancellor approved, and 1 April 24, 1923, with due respects the egg-plastered professor the engineering Exposition was born. From this unspectacular beginning, e Exposition has developed into event which attracted more than 50,000 to the major exhibits from the departments of the School of Engineering, the mathematics department and the military sciences are expected to attract as many this year. Some of today's exhibits appeared in similar form in the earliest expositions. Through the years, however, there has been a large variety of tricks, gimmicks, and informative displays designed to illustrate scientific principles to the layman. In 1925, Fluers Des Kansas was manufactured to rival the producers of Chanel No. 5. The same year six army planes from Fort Riley staged a mock battle over the University, to rival the engineers'-lawyers' feud. Not content with the Rock-chalk yell, the engineers came up with their own in 1929 and called it "hyperbolic paraboloid," which became the official yell for the exposition of that year. A real contribution to all students was made in 1941 when Theta Tau, honorary engineering fraternity, invented a gadget designed to keep students awake in class. A rope was placed around the neck of the student. When he nodded, the rope jerked, opening a trap door from which rolled a ball, which knocked over some ten pins. Eventually a tack came up through the chair to awaken the sleeper. In 1949 a pipe organ was built from beer bottles. Last year's show hit the ceiling with a smoke-eater, flying saucer, robot, disconnected faucet, and a kiss-o-meter. The exposition has been an annual event with the exception of 1926, 1933, and the war years from 1942 to 1947.
