They wanted to make new kinds of Roller Coasters just like they wanted to make them higher.
Roller coasters have wheels bolted onto three different sides of the track, so it would be impossibe to fall off the tracks.
the wheels are covering the trach
Yes
A part where the riders go upside-down.

Runaway Mountain does not go upside down.
No, Expedition Everest (Disney) doesn't go upside down but it dose make you get that feeling that you are.
The Incredible Hulk roller coaster goes up-side down 4 times last for up to 7 seconds each time.
no but it feels like you will hit a pole or bar but you wont.
No, sadly it does not. My older brother really wanted it to go upside down and was disappointed that it didn't.
At Universal Studios no roller coasters go up side down. But at Universal's Islands Of Adventure the roller coaster that go upside down are: The Incredible Hulk Roller Coaster and Dragon Challenge (both sides). The Incredible Hulk Roller Coaster has a Zero-G roll, a Cobra Roll, a Vertical Loop, a Corckscrew, a smaller Vertical Loop, and another Corckscrew. On the Chinese Fireball at Dragon Challenge it has 2 Immelmanns, a Vertical Loop, and two Corckscrews. On the Hungarian Horntail is has a Zero-G roll, a Cobra Roll, a Vertical Loop, and a Corckscrew.
the gravity will pull the roller coaster down a little bit and then it might go a little slower.
It depends on which roller coaster you go on. for the more extreme ones, you have to be taller. for littler ones you still have to be a certain height but not as tall as the more extreme ones.
To keep fun!
