When one inserts a hole at the bottom (by removing a marble), the hole will float all the way up, with marbles going one step down one by one. A fractal hexagonal design was chosen because of uniformity and hence ease of design. At each step, marbles change direction by 60 degrees. This way, marbles always push marbles in front, but not too hard. Also, the design allows for high walls that prevent the marbles from jumping out, which in turn allows a steeper track such that marbles never get stuck. Copyright (c) 2026, M. Oskar van Deventer.
