1. ## He measured the time by catching drops of water while a ball rolled

I'm sorry this might be a science question. Did Galileo spread some water on the surface of the ramp and measured the amount of the water that dripped? So did more water mean more time? I don't get it.

ex)There is a story that Galileo dropped two different weights off the Leaning Tower of Pisa, which may or may not be true. But we do know that Galileo was very clever in the way he measured how things fall. When Galileo lived, about 400 years ago, there were no watches or clocks. Any falling object fell too fast for him to measure how long it took. So, Galileo decided to slow down falling objects. Instead of dropping objects off buildings, he decided to roll balls down a ramp. He figured that the same force that made things fall would make balls roll down a ramp. This force is called gravity. A ramp would make it easier to. He measured the time by catching drops of water while a ball rolled. He could change the steepness of the ramp and measure the distance the ball traveled while water dripped. The steepest ramp was very close to a free fall.

While the ball was rolling, Galileo recorded the time taken by using a simple form of water clock.
