Invisible Air Pressure | Atmospheric Pressure Song for Kids

At our picnic, what can hold the water? The atmosphere is air around the Earth. With an adult, I fill a plastic cup. A stiff card seals the opening tight. I flip it over above the bowl. I let go; the card stays beneath the cup. Gravity pulls; the water doesn't spill. Air presses in from every side. From below, from the sides, from above. That's atmospheric pressure. Though unseen, the card reveals its push. Outside air pushes the card upward. Inside the sealed cup, pressure is lower. The stronger outside push helps hold it there. Gravity still pulls the water down. The pressure difference solves the riddle. Air presses in from every side. From below, from the sides, from above. That's atmospheric pressure. Though unseen, the card reveals its push. I lift one edge; air enters the cup. The pressure difference becomes smaller. Card and water splash into the bowl. Air presses in from every side. From below, from the sides, from above. That's atmospheric pressure. Though unseen, the card reveals its push. Invisible air presses all around.
