An awesome Roller Coaster.
In this world you spawn underground. You can click the button which will spawn a Minecart on the rail, then you just need to go forward. All the rails are powered with Redstone, so it will go for you. When you start going, you will go up and up and then you'll go down really fast. At the start and end of the Roller Coaster there is some water that you go into, but you won't drown.
