The Leidenfrost Effect: How to Make a Liquid Levitate

The video explores the Leidenfrost Effect, a phenomenon where a liquid hovers over a surface much hotter than its boiling point, forming a vapor cushion. This effect, named after Johann Leidenfrost, allows droplets to move with minimal friction, leading to potential applications in various technologies. Scientists have experimented with controlling droplet movement, creating mazes and using hydrophobic surfaces to lower the temperature needed for the effect. These advancements could impact fields like micro cooling and inkjet printing.
