The only glitches used were the slope-phase glitch (which makes them magically appear). Despite what it looks like, the propeller is not actually a booster. It hits the cart on the tracks, which is then hit against the other carts in the stack, thus causing momentum. Physics man. SCIENCE.
I used the Too Many Items mod, and Single Player Commands mod. Besides this, no actual hacks were used in the game.
Fun Fact: After I filmed this, it immediately started raining.
