First get a car and go to the swingset in Firefly projects. When you get there, 
drive your car up the middle bar. if you do it wright you should go flying. You 
can also do this on a bike or you can do it while you are standing up. if you 
do it while you stand up just go under the bar and jump. when you jump up it 
might kill you.
