An anti-dribble valve is like a tiny gate that can open and close the pathway for liquids to flow through. It is usually used in a sports game called basketball, when a player stops dribbling the ball and holds it in their hand.
Before the ball is held still, it bounces on the court and dribbles because of the force applied by the player's hand. This force makes the ball release some of the liquid or air inside it, causing it to soften and ultimately affect the player's grip and control.
To prevent this from happening, anti-dribble valves are used in basketballs. When the ball bounces, the valve allows some air to escape gradually, which makes the ball remain bouncy but not too soft to handle. When the player decides to hold the ball, the valve closes, preventing more air from escaping and making the ball stay inflated and firm.
So in summary, the anti-dribble valve is like a little gate in a basketball that controls the air flow to make the ball easy to dribble but still grips well when held.
