Kind of like Haunted Mansion.

Since 1991 “the Ig Nobel Prizes honor achievements that first make people laugh, and then make them think.” Fluid dynamics won two prizes this year in the category Physics Prize and in the Fluid Dynamics Prize. The first one concerned a question that you probably have wondered about watching cats online: “are cats fluid or solid?”. This question was tackled by Marc-Antoine Fardin of Univ. of Lyon in 2014 [1] where he discusses the solid and fluid like behaviours of Felis Catus (or simply cats). In the first picture you can see different state of the Felis Catus materials: a) a solid state and (b-d) a fluid state. The second concerns a particular fluid, awarded of now three prizes by the community: COFFEE! [2] The first fluid dynamics prize on spilling coffee was awarded in 2012 to H. Mayer and R. Krechetnikov [3]. In the second picture, Jesse gave away a technique to record the acceleration of your coffee cup! Simply use your phone (and an apps like #phyphox). You better be in a not-spilling regime… [1] M.A. Fardin, On the rheology of cats, Rheology Bulletin, 83(2) July 2014 [2] J.
