text: After a talk by Lage-Castellanos at the First Workshop on Complex Matter Physics in Havana (MarchCOMeeting'2012), professor Troy Shinbrot of Rutgers University became interested in the subject. Together with student Theo Siu, Cuban results were confirmed and expanded with new experiments and numerical simulations at Rutgers, which resulted in a joint peer-reviewed paper.
  Later on, the phenomenon was confirmed independently by others. Whether dynamical behaviors of the falling water play a role remains as an open question.
  Videos of the effect are available on YouTube.
