The video explores the physics of finger snapping, revealing it as a complex and fast movement. Researchers identified three phases: loading, unlatching, and the snap itself, with friction playing a crucial role. The study's findings could aid in understanding insect jaw snaps and improving prosthetics. The video concludes with a promotion for Brilliant's educational courses.
