1. Leviatation

The woman lays on a board which is held up by a metal rod. The magician stands to hide the rod, so where he is standing determines how well the trick is executed.

3. Zig Zag Girl

This trick is actually quite simple. When the assistant steps into the box she turns her body sides ways so that when the blades go in, they slide right past her body. When the mid section of the box is pushed out, only her hand goes with it, but the black lining of the box gives the illusion that her midsection has completely shifted.

4. Into The Air

This trick is very similar to the other levitation trick but the magician does not stand in front of the support. He then passes a hoop over the assistant only going as far as the support allows which gives the illusion that the body is floating in the air.
