How to fly after you ramp and hit the water:
When you are ready to ramp make sure u are going fast, then right after u get in the air let go of the gas and press and hold the break than quickly press and hold the boost.
Keep holding than when u hit the water keep holding and u should bounce and fly for a few seconds it really cool.
(NOTE: this only works if you have some boost.
Thanks for doing this code.
