The Deeper You Go, the Harder It Pushes

You'll learnhow pressure in a still fluid grows with depth, whatever the container's shape.

Nothing touches a diver's ears but water — and yet at five meters they're shouting. Watch pressure grow one meter at a time, prove the container's shape never mattered, and learn which of the two pressure numbers your ears actually feel.

Before you start

What you're looking at

A probe on a depth ruler in water (ρ = 1000 kg/m³), with 100 kPa of atmosphere resting on the surface.

The question

What are your ears measuring as you dive deeper, and does the pool's shape matter?

Watch for

Pressure climbing one meter at a time; two readouts separate gauge pressure from absolute.

What the symbols mean

Dashed lines mark depths (2 m, 5 m); readouts give gauge and absolute pressure in kPa.
