Invisible Air Pressure | Atmospheric Pressure Song for Kids

◷ 3:09

Can invisible air help hold up water? This upbeat science song shows how the atmosphere surrounds Earth and how atmospheric pressure acts from every direction. Children discover how pressure differences and gravity affect a card-covered cup. Try the demonstration only with an adult, over a bowl, using an unbreakable cup when possible.

Pressure

Pressure is perpendicular force per unit area: pressure = force ÷ area. The same force acting on a smaller area produces greater pressure.

Song lyrics
En el pícnic, ¿qué sostiene el agua? La atmósfera envuelve la Tierra: es aire. Con un adulto lleno un vaso de plástico. Una cartulina firme sella la abertura. Lo volteo sobre un tazón grande. La suelto: queda bajo el vaso. La gravedad tira; el agua no cae. El aire presiona por todos lados. Por debajo, a los lados y arriba. Es la presión atmosférica. No se ve; la cartulina da la pista. El aire de fuera la empuja hacia arriba. Dentro del vaso, la presión es menor. El mayor empuje de fuera la sostiene. La gravedad tira del agua hacia abajo. La diferencia de presión lo explica. El aire presiona por todos lados. Por debajo, a los lados y arriba. Es la presión atmosférica. No se ve; la cartulina da la pista. Alzo un borde; entra aire en el vaso. La diferencia de presión disminuye. Cae la cartulina; el agua salpica. El aire presiona por todos lados. Por debajo, a los lados y arriba. Es la presión atmosférica. No se ve; la cartulina da la pista. El aire invisible presiona alrededor.
Language version lyrics
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.

Push Harder, Change Motion! | Newton’s Second Law Song for Kids

This upbeat children’s song uses a toy cart to show how force and mass affect acceleration. Kids discover why a stronger net force changes motion faster at the same mass, while added mass produces less acceleration under the same force. It also introduces the simple relationship F = ma.
