This isn't WDW, but can someone give me a run down on how the portable hole effect works in Car Toon Spin? I'm assuming the "hole" is on wheels and moves back but when you enter the room it seems like the hole and the wall are clearly separate somehow. Also just while I'm on the topic of this ride: I'm assuming the urban myth of the ride's inspiration coming from Imagineers putting a tea cup on a Fantasyland ride late at night is untrue correct? As it would be impossible to just stick a new vehicle, especially a tea cup on an existing rides track? Thanks.
