Wall Tension
- Description:
- Partly inflate a cylindrical balloon so that a nipple remains on the uninflated end. Press each part of the balloon. Is the air pressure the same everywhere inside? Pascal's Principle says yes--otherwise air would flow from high pressure to low pressure. When you press, could the stretched skin of the inflated balloon be putting a force on your finger? See Wall Tension from Hyperphysics.
