Moving Hall by JL Magic (6396)

You show a plastic strip in the colors black and white. The outer sides black, the middle part in white. There is a hole in one of the black boxes on the outside, you take a straw and put it through to show that it is a real hole. Then you take out the straw, rub your hand over the hole on the black part and move this hole to the white box in the middle!

Again you take the straw and put it through the hole. Then you take the hole again and now move it to the other ends in the black box and put the straw through it again.

Then you put the hole back to the white box and put the straw through again and then put everything away, but wait, what if someone wants to examine everything? No problem, take it back out of your pocket and hand over everything for examination.

You will receive everything you need to perform this visual trick and a link to an online instructional video. Hardly any practice is required as it is virtually self-contained.
