I am stuck where you go in the professors ball gadget. I with though the turning post and back to where the poles come out of the ground they go up and down. I read in the walkthrough that when you get up on the ledge that you are at the in that there is a crack in a wall and your out. I can not find any crack and I dont know how to get out of this part. I rolled up where there is a open window ledge and jump out only to have the turning poles to stop me. I tried where the dip is back by the poles that come up and down in the ground and nothing the walls where you have a choice to stay in the ball or out there is a dip in the ground where there is one pole going up and down and on the other side there is 3 poles going up and down in the ground.the walls on each side of the dip I tried to roll up it with no luck. can you tell me how to actually get out of this area?
