This year we decided to join forces with our colleagues from the University of Navarra in Spain and submit a joint video about jamming and clogging in hourglasses and in hourglasses-like systems.

The video will be presented formally in the annual APS-DFD in Portland in November, and I hope to have submitted the bloody paper by then!

We also have narration this time! So you’ll hear Angi from Munich and me from Enschede narrating the video… Enjoy!
