How does the WWE make the Undertaker disappear?

Answer 1

They turn off the lights and he usually comes from under the ring and appears in the ring

If undertaker waits under the ring it will take him to long to wait unti the show is over, remember when he won the royal rumble in 2007 and at Raw you can see tham he is saw cena and he was standing on something that took him up and down and maybe that's how he disappear so fast or he runs up the rump and goes backstage, By:5913253122
