In this post we have written on how to make heart working model | inspire award science project – diy easily | blood circulation | howtofunda
This simple model demonstrates the basic function of the heart, how blood flows through the chambers, and the role of valves in preventing the backward flow of blood
Creating a heart working model using two bottles is an excellent way to understand the basic functioning of the heart and its role in the circulatory system.

Video Step by Step on Making Heart Model using Bottles
In this project, we’ll create a basic working model of a heart using two bottles, two plastic cups, and pipes to represent blood flow. Here are the steps:
- Two plastic bottles (empty and clean)
- Two plastic cups
- Flexible pipes or tubing (preferably red to represent blood)
- Red and blue food coloring (optional, for visual effect)
- Hot glue gun or strong adhesive
- Cardboard (optional, for base)
Building the Heart Model:
1. Preparing the Bottles:
Step 1: Select one of the bottles to represent the right atrium of the heart. This will be the upper chamber that receives deoxygenated blood.
Step 2: Cut off the top of the bottle to create an opening.
Step 3: Select the other bottle to represent the left ventricle. This will be the lower chamber that pumps oxygenated blood.
Step 4: Cut off the top of the bottle to create an opening.
2. Creating Valves:
Step 5: Cut the bottom of one plastic cup and hot glue it to the opening of the right atrium bottle. This will serve as the tricuspid valve.
Step 6: Cut the bottom of the other plastic cup and hot glue it to the opening of the left ventricle bottle. This will serve as the bicuspid or mitral valve.
3. Connecting Blood Vessels:
Step 7: Attach the flexible pipes or tubing to represent blood vessels. Connect one end to the right atrium and the other end to the left ventricle.
Step 8: If available, use red food coloring in the tubing connected to the left ventricle to represent oxygenated blood, and blue food coloring in the tubing connected to the right atrium to represent deoxygenated blood.
4. Securing the Model:
Step 9: Use hot glue or strong adhesive to secure the connections and prevent any leaks.
5. Optional Base (if needed):
Step 10: If you wish to display the model on a base, cut a piece of cardboard to fit the bottles and glue them in place.
Your basic heart working model is now complete!
When you squeeze the left ventricle, it simulates the pumping action of the heart, pushing “blood” through the valves and into the right atrium. This simple model provides a visual representation of how blood flows through the heart’s chambers.
