How to Build Your Own Water Clock IELTS: A Beginner’s Guide

Building a water clock is a rewarding DIY project that combines science, physics, and engineering. Follow these simple steps to create your own water clock using easy-to-find materials and tools.

Materials needed:

  • Clear plastic or glass tube (3-4 inches in diameter)
  • Clear plastic or glass rod (2 inches in diameter, 10 inches long)
  • Clear plastic or glass ball (1 inch in diameter)
  • Water-tight glue
  • Scissors
  • Ruler

  • Marker or chalk
  • Tape measure
  • Stopwatch


  1. Cut the tube to your desired length using scissors.
  2. Mark a point on the tube where you want the water level to be using a marker or chalk.
  3. Apply glue to both ends of the rod and attach it to the inside of the tube, leaving enough space for the ball to float freely.
  4. Fill the tube with water and place the clear plastic or glass ball at the marked point.
  5. Measure the time it takes for the ball to move from one end of the tube to the other using a stopwatch.
  6. Adjust the angle of the rod as needed to achieve the desired time for the water level to reach the opposite end of the tube.
  7. Secure the rod in place with additional glue if necessary.

Your water clock is now ready!

Experiment with different angles and lengths of the rod to see how they affect the time it takes for the ball to move through the tube. You can also add food coloring or other substances to the water to make your clock more visually appealing.
