Ig Nobels Harvard
Koji Tsukada yells into his invention the "SpeechJammer" during a performance at the Ig Nobel Prize ceremony at Harvard University, in Cambridge, Mass., Thursday, Sept. 20, 2012. The Ig Nobel prize is an award handed out by the Annals of Improbable Research magazine for silly sounding scientific discoveries that often have surprisingly practical applications.
