You could make a track with two coat hangers and have a marble roll along the two rails.

I extremely have an concept which will artwork yet won't be perfect, besides the undeniable fact that, that is properly worth a attempt. i might purchase a 6 foot length of sparkling plastic tubing with a diameter greater than the marble. . The tubing might desire to be curved right into a loop and mounded on a chunk of Peg Board using the holes interior the board as a tie down factor. i might use very small 'Tie Wraps" to take care of the tube to the board. Run the Tie Wrap from the lower back area around the tube and lower back by using the board and pull tight. you could then tilt the board at any attitude so the marble will make the loop. All components could be bought from domicile Depot
