Want to see the magic trick that made Kanye West, Bryan Cranston, Aaron Paul and Will Smith all cringe and recoil?

In a newly posted clip from his 2013 documentary David Blaine: Real or Magic, the street magician keeps his celebrity audience members on pins and needles as they give him a hand with a particularly sharp trick.

Watch it in the video above, but be warned — whether real or magic, the trick involves an ice pick and is not for the faint of heart or queasy of stomach.
