Materials:
1. Cardboard box or foam sheet
2. Scissors or utility knife
3. Paper or plastic cups (for wheels)
4. String or rubber bands (for axles)
5. Foam padding or bubble wrap
6. Glue or adhesive tape
Instructions:
1. Chassis Design: Cut the cardboard or foam sheet into a rectangular shape for the car's base. Ensure it's large enough to accommodate the egg and some padding. Make necessary folds to create the car's shape.
2. Egg Compartment: Cut a small, egg-sized opening in the center of the car's base. Glue foam padding or bubble wrap inside this compartment to cushion the egg.
3. Wheels and Axles: Attach paper or plastic cups to the car's base to serve as wheels. Use string or rubber bands as axles to connect the wheels and allow them to rotate freely. Make sure the wheels are evenly balanced.
4. Shock Absorbers: Cut small pieces of foam or bubble wrap and place them between the chassis and the wheels to act as shock absorbers.
5. Egg Support: Add additional padding around the egg compartment to ensure the egg doesn't move too much during the descent.
6. Testing: Before placing the egg in the car, test it by rolling it down the ramp without the egg to make sure it moves smoothly and doesn't tip over.
7. Final Assembly: Carefully place the egg in the egg compartment and secure it using a foam or bubble wrap cover. Close the car's body to ensure the egg is stable.
8. Ramp Setup: Set up a ramp with a gentle incline. Make sure the ramp is smooth and free from obstacles.
9. Descent: Position the car at the top of the ramp and let it roll down. Observe how the car's shock absorbers and controlled descent ensure the egg remains intact.
Remember, this is a simple design, and there can be many variations to improve its performance and safety. Experiment with different materials and cushioning techniques to optimize the car's design for your specific ramp and egg. Have fun and be creative!
