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.
Original explanations based on the cited sources.
Pressure is perpendicular force per unit area: pressure = force ÷ area. The same force acting on a smaller area produces greater pressure.

2:28How can invisible air give a balloon its shape? This upbeat science song shows a pump pushing air inside, the air pressing on the stretchy rubber, and one balloon slowly growing.
2:15This 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.
