How to spill coffee: a science demonstration

Neuroscientist Gustav Nilsonne demonstrates how and why it’s difficult to walk while carrying a cup of coffee. This photo was taken at last night’s Ig Nobel show at the Karolinska Institute in Stockholm Sweden. The physics of this led to an Ig Nobel prize being awarded year to Rouslan Krechetnikov and Hans Mayer for their study “Walking With Coffee: Why Does It Spill?” [Physical Review E, vol. 85, 2012]. The photo was taken by Ig Nobel Prize winner Kees Moeliker, who also was part of last night’s show.
