Creating an intricately designed marble run spiral with two columns involves building a challenging and exciting obstacle course for marbles to navigate through. This activity requires patience, creativity, and precision, making it an excellent learning experience for children who enjoy building and problem-solving. By following simple instructions and utilizing basic materials such as cardboard, tape, and scissors, individuals can build their own marble run spiral with two columns and enjoy the thrill of watching marbles successfully complete the challenging course. Key Requirements: • 1 large piece of cardboard • 2 shorter pieces of cardboard for columns • Scissors • Glue or hot glue gun • Tape ( masking or packing) • Marbles Step-by-Step Instructions: **Setting Up the Columns:** Begin by cutting two smaller rectangles from cardboard to create the column bases. These will provide stability and structure to your marble run. Next, attach the shorter cardboard pieces together with glue or a hot glue gun to form an upright vertical base. This will ensure that both columns are secure and balanced. **Assembling the Spiral Track:** To create the spiral track, use scissors to cut several curved lines from the remaining cardboard material. Make sure each piece is roughly 2-3 inches long. Cut multiple spirals with equal curvature but different starting points for your spiral curves will enable a natural-looking shape in your marble run. Attach the individual cardboard strips together using glue or tape, weaving them to form the distinctive twisted pathway that defines the heart of your Marble Run Spiral. Secure each section as you go and leave some small holes here so air can pass through for proper cooling. **Adding The Finishing Touches:** Apply clear tape along all parts and test how securely attached it is, taking care not to block access with debris or obstacles during play. Insert a handful of marbles into the start column, close to but still separate from the exit channel in this spiral marble track and have fun running. To optimize safety make sure both marbles remain well spaced and always on opposite sides.
