In this OID Film, Yufan Xu makes a batch of "Barbasoloscope" visualization fluid, approximately following the recipe given in Borrero-Echeverry et al. Physics of Fluids, 2018.
CRUCIAL: WE MADE A BIG MISTAKE AT 3:00! EITHER PAPER TOWEL OR COFFEE FILTER MUST BE PLACED IN THE FUNNEL IN ORDER TO REMOVE THE OILS FROM THE MIXTURE. Since we did not remove the oil, it forms a capping layer that essentially minimizes the visual effects of the Barbasoloscope. Which is exactly what we do NOT want to have happen.
With correctly filtered Barbasoloscope, one can make movies like this one: youtu.be/LMvHbU86akU.
