how to make syphon self starting science project

In this blog article we have given information on how to make syphon self starting using waste materials available at home for inspire award science project

Creating a self-starting siphon science project using a straw, pipe, and plastic tray is an interesting experiment to demonstrate the principles of siphoning and fluid dynamics.

Here’s a step-by-step guide to help you build this project:

Materials Needed:

  1. Straw: One regular-sized drinking straw.
  2. Flexible Pipe: A piece of flexible plastic tubing, around 1 meter in length.
  3. Plastic Tray: A shallow plastic tray or basin to hold the liquid.
  4. Water: To demonstrate the siphoning action.
  5. Scissors: For cutting the tubing.
  6. Tape: To secure the tubing.
  7. Marker: For marking the tubing (optional).

1. Prepare the Tubing:

  • Cut the flexible plastic tubing to the desired length. It should be long enough to reach from the bottom of the tray to a lower point where the water will flow out.
  • If desired, mark one end of the tubing with a marker to indicate the starting point of the siphon.

2. Set Up the Tray:

  • Place the plastic tray on a flat surface.
  • Fill the tray with water, ensuring it is deep enough to cover the end of the tubing.

3. Create the Siphon:

  • Insert one end of the straw into the water in the tray, ensuring it is fully submerged.
  • Place the other end of the straw into your mouth and start sucking to draw water up into the straw. Once water fills the straw, quickly remove it from your mouth.

4. Start the Siphon:

  • While keeping the straw’s end elevated above the tray, quickly insert it into the flexible tubing.
  • As the water flows out of the straw and into the tubing, gravity will take over, and the siphon will begin.

5. Observe the Self-Starting Siphon:

  • Once the siphon starts, observe how the water flows continuously from the tray, driven by gravity and atmospheric pressure.
  • You can measure the rate of flow or observe any changes in the water level in the tray over time.


This self-starting siphon science project is a simple yet effective way to demonstrate the principles of siphoning and fluid dynamics. It’s a hands-on experiment that provides insight into how siphons work and the role of gravity in moving fluids. Enjoy conducting your experiment!
