Place a trampoline at the highest possible point above any planet's surface when making a new adventure.
use TAB to tilt it 90 degrees so that if you draw a line straight from the upper side it would make a horizontal line trough the screen.
Now place your player on it, set the trampoline to full power and enjoy the spectacle.
NOTE: before placing the player you should make sure you can't see the ground behind the trampoline. Instead you must see space. If you see ground behind the trampo and try to place your player on it it will be placed on the surface beneath.
