The Vox Box is a really cool way to vanish an object and make it reappear inside the box. It's nice
because you can show that the box is empty first. There are no duplicates used here. You can borrow
a quarter, have it signed and it appears inside of the box. On the downside, the box can't be
examined but then again, it's just a box. Most people won't be interested in checking it out
anyways.
