Enable the "All emeralds", "Level select", and "Debug mode" codes, then go to Oil Ocean (either act). Become Super Sonic and stand on one of the green/yellow colored cylinders. Jump on it and as soon as you hear it break, go into debug mode. You should be thrust upward, even in your debug state. As soon as you regain traction, exit debug mode to be able to jump twice as high and fast.
