[00:00:00]Why do rockets get showered with massive amounts of water [music] during liftoff?

[00:00:03]It's not mainly to cool the engines or put out flames. During launch, rocket engines generate extremely [music] powerful sound waves strong enough to damage nearby structures and even the rocket itself. [music] To prevent this, engineers use a water deluge system built into the launch pad.

[00:00:17]Just seconds before liftoff, nearly 2 million liters of water are released across the pad in [music] under a minute. The water absorbs and disperses the intense acoustic energy produced during ignition. Without it, the sound vibrations [music] alone could interfere with sensitive equipment. That's why every rocket launch begins with an enormous [music] flood of water beneath the engines.
