Wearing a toilet seat on his head, David Hu, Associate Professor of Mechanical Engineering and Biology at Georgia Institute of Technology, walks away with his team's Ig Nobel Prize in Physics for testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds) at the 25th First Annual Ig Nobel Prizes awards ceremony at Harvard University in Cambridge, Massachusetts September 17, 2015. The annual prizes, meant to entertain and encourage global research and innovation, are awarded by the Annals of Improbable Research as a whimsical counterpart to the Nobel Prizes.
