What are water clocks?

Water clocks are containers that measure time using water, just like how you might use a glass to measure how much juice you drink.

Imagine you have a bucket with a small hole at the bottom, and it’s slowly leaking water into another empty bucket. As time passes, more and more water flows through the hole. You can tell how much time has passed by looking at how full the second bucket is, the more water there is, the longer the time.

Water clocks usually have a container that holds water, and they let it drip out slowly. Sometimes, people would fill them up with water every day so they could measure hours or even whole days. It’s like having a slow-flowing tap that you can watch as it fills up another container, the longer it runs, the more time has passed.

Even though we now use digital clocks, water clocks were used for thousands of years! People in ancient Egypt and China used them to know when to start work or go to bed. It’s like using a water version of a timer, simple but smart. Water clocks are containers that measure time using water, just like how you might use a glass to measure how much juice you drink.
