Glycerine dripped onto dry ice demonstrates the Leidenfrost effect as the dry ice sublimates, forming a gas layer.
A Worthington jet forms when the wake of a droplet falling into water collapses. Here, a colored backdrop is reflected.
The Rayleigh-Plateau instability describes the breakup of a falling stream, here seen just before impact with a Worthington jet.
Just after impact, a droplet forms a ‘crown’ splash. Then the droplet wake collapses and forms the Worthington jet.
Water trickles down a ‘Zen Board’, turning the top surface transparent and allowing the black backing to show through.
