What comes up, must come down. That’s typically how it goes for matter on Earth, due to the force of gravity. Steve Spangler of Sick Science! demonstrates that it doesn’t always have to work like that.

What prevents the water from leaking out? Is it the fabric of the handkerchief? Spatial cohesion? Air resistance? Discuss it in the comments!
