This gets Mario to jump strangely... not so exciting, though. In the main world, jump. While in mid air, bring up up the time machine. Then, use it and go through the surfing game. Go through any whirlpool. When you get back to the main world, Mario will be in jumping position but on the ground and then warp upwards and then fall down. Also, if you're facing to the left, this will make you face to the right.
