I'm guessing it works the same way they did the transporter bit for the old Star Trek Experience: all the flashing lights kills your night vision so you don't notice the walls being retracted.
@@blackjac5000 while I agree with this, you can’t hear a damn thing moving and obviously walls are moving but HOW ARE THEY SO QUIET?! I couldn’t help myself but exclaim “WHAT?!” When I experienced this. I was flabbergasted lol
@@blackjac5000 no not at all which is why I was so…..confused 🤣 you’re just blinded by the flashing lights which is understandable considering the “effects” but I was literally by the wall inside the circle they told my to stand by (there was quite a bit of people in the room) it all goes quiet and then I’m in a different room all together and I couldn’t believe what happened.
You say that like Disney has animatronics in all their preshows. They don't. The reverse isn't true either. Gringotts? Kong? Velocicoaster? All have animatronics in their queues.
