In this post we write about making of the escalator working model – elevator diy – science project for exhibition using cardboard
Creating a working model of an escalator using cardboard, paper, and chopsticks is an interesting project that demonstrates the principles of mechanical movement and engineering. Here’s how you can build this model:
Materials Needed:
- Cardboard
- Paper
- Chopsticks (or wooden skewers)
- Rubber bands
- Tape or glue
- Scissors or craft knife
- Ruler
- Pen or pencil
- Small toy figures (optional, to demonstrate the escalator)

- Prepare the Base Structure:
- Cut the Base: Cut a rectangular piece of cardboard to serve as the base of your escalator. The size can vary, but a piece about 12 inches by 6 inches works well.
- Side Supports: Cut two identical triangular pieces of cardboard to serve as the side supports. These will hold the chopsticks in place and form the angle of the escalator.
- Assemble the Side Supports:
- Attach Side Supports: Glue or tape the triangular side supports to the base. Position them at an angle to mimic the slope of a real escalator.
- Prepare the Axles:
- Chopstick Axles: Cut two chopsticks to the width of the base. These will serve as the axles for the escalator steps.
- Mount Axles: Poke holes through the side supports near the top and bottom. Insert the chopsticks through these holes, ensuring they can rotate freely.
- Create the Escalator Steps:
- Step Treads: Cut several rectangular pieces of cardboard to serve as the steps of the escalator. The width should match the distance between the side supports, and the length should be about 1 inch.
- Attach to Rubber Bands: Tape or glue the steps to rubber bands. Space them evenly along the rubber bands to create a continuous loop of steps.
- Assemble the Moving Steps:
- Attach Rubber Bands: Stretch the rubber bands with the steps around the top and bottom chopstick axles, forming a continuous loop. Ensure the steps are evenly spaced and positioned horizontally.
- Secure the Rubber Bands: Use additional tape or glue to secure the rubber bands to the chopsticks if necessary, ensuring they do not slip during rotation.
- Create the Handrails:
- Handrail Guides: Cut two thin strips of cardboard to act as the handrails. Attach them along the top edge of the side supports.
- Handrail Movement (optional): If you want the handrails to move, you can attach thin strips of paper or additional rubber bands along the path of the handrails, mimicking the movement of a real escalator.
- Test the Escalator:
- Rotate the Axles: Manually rotate the chopsticks to move the rubber bands and steps. Observe how the steps move in a continuous loop, simulating an escalator.
- Adjustments: Make any necessary adjustments to ensure smooth movement. You may need to adjust the tension of the rubber bands or the positioning of the steps.
Explanation of the Science:
- Mechanical Movement: The escalator model demonstrates how steps can move in a continuous loop using axles and a belt mechanism (rubber bands).
- Rotation and Tension: The chopsticks act as axles, and the rubber bands act as the belt that moves the steps. Proper tension is crucial for smooth movement.
