Running on Water: Science Behind the Basilisk Lizard

The video explores the concept of running on water, starting with the mythical basilisk and moving to real-life lizards that can run on water due to physics, not magic. It explains the science behind why small animals can walk on water using surface tension and how larger animals like basilisks and grebes use specific techniques to run on water. The video then discusses the challenges humans face in running on water due to the need for immense force and how it might be possible in low-gravity environments like the moon. Finally, it concludes with a promotion for SciShow.
