When the water tap is closed with our fingers jets of water gush through the space between fingers with high speed. Why?

Explanation

To understand why jets of water gush through the space between our fingers with high speed when we close the water tap with our fingers, we can analyze the situation using the principle of continuity in fluid dynamics.

### Step-by-Step Solution:

1. **Understanding the Principle of Continuity**:
The principle of continuity states that for an incompressible fluid flowing through a pipe, the product of the cross-sectional area (A) and the flow velocity (v) at any two points along the pipe remains constant. This can be expressed mathematically as:
\[
A_1 \cdot v_1 = A_2 \cdot v_2
