He is TETHERED, you can GET HIM
Illusionist David Blaine hangs upside down at Wollman Rink in Central Park on September 22, 2008 in New York City. The 35-year-old Blaine planned to hang for 60 hours from a wire, completing the stunt on September 24.
I CALL FOR ANY NEW YORK ONTD MEMBER TO GET A DAMN FANSIGN. HE IS ATTACHED TO A WIRE, HE IS NOT GOING ANYWHERE.
And according to Inside Edition (which is on right now) there is possibility for him to suffer a STROKE or go BLIND, so that'll be exciting to witness if you go.
