An impossible routine! The magician passes his arm through a black box, showing it empty to the audience.
Now he dramatically pushes down a blade through his wrist! Another wave and he passes a second blade through his arm!
The magician turns his arm and pulls out the wall of the box.
Zig-zag happens! But his arm is miraculously unharmed!
The Zig-zag Guillotine will make the audiences scream in fear, then applaud in amazement and surprise!
