If you've ever wondered how Brazil nuts always seem to end up at the top of your mixed nuts, this is the video for you! In this FYFD video, Nicole explains the Brazil nut effect and granular convection. ---------- Follow FYFD on: Tumblr: http://fyfluiddynamics.com/ Twitter: http://twitter.com/fyfluiddynamics Thanks to my Patreon patrons and FYFD supporters who help make FYFD and FYFD video possible!
