Sam Rottenegger got some free tickets to go and see his least favourite band. Sam, feeling a little unruly, stopped at the corner store. So, he could bring a 1/2 dozen eggs with him to the concert. The concert was packed and the tunes were so loud that Sam could hardly stand it. He started making his way through the crowd when one of the eggs broke in his pocket and ran down the inside of his shirt. Sam squirmed with disgust but thought how great it would be to see that yellow ooze on the band members. It took him 60 gruelling minutes to make his way close enough to launch his attack. Sam chucked one right at the bass player but it just bounced off him without breaking. “Odd,” Sam thought, but every one of the 4 eggs he threw just landed unbroken. He never got to throw the 5th as security removed Sam promptly. Sam, now half deaf, bruised, battered and confused, looked closely at the egg and noticed it wasn’t exactly raw any more. Frustrated, Sam chucked the egg over his shoulder hitting an officer who gladly gave him a free night- stay at the Bars Inn.
So what happened to the eggs that caused them not to break? Note that they were totally raw when he brought them in.
High-volume sound waves at certain frequencies can cause the proteins in an egg to stick together almost like when it is boiled. Thus the eggs bounced like a hard-boiled egg instead of breaking.
