Why will waterhose splashed so high?

Water hoses can splash high due to the pressure of the water being expelled from the nozzle. When the nozzle is narrowed, it increases the velocity of the water, causing it to shoot out with greater force. Additionally, if the hose is held at a certain angle, gravity can help propel the water higher into the air. Factors like water pressure and the type of nozzle used also play a significant role in the height of the splash.
