You can move in any direction in a fluid at rest without the pressure changing.

Here's why:

* Pressure is a scalar quantity: This means it has magnitude but no direction. It acts equally in all directions at a given point in a fluid.

* Fluid at rest: In a stationary fluid, the forces due to pressure are balanced. This means the pressure is constant throughout the fluid.

Therefore, no matter which way you move in a fluid at rest, the pressure will remain the same.
