'AGT' Trapeze Artist Plummets During Blindfold Trick Over Fire

An "America's Got Talent" husband and wife duo felt the burn ... when their blindfolded trapeze trick -- over open flames -- came to a shocking end.

Mary and Tyce were flying through their act on Tuesday night's broadcast, pulling off some amazing stunts on a trapeze ... and even amped things up with a fire pit. The act took a turn though -- when Tyce slipped on a blindfold.

While hanging upside down, he was supposed to grab his wife as gravity pulled her down over his body -- but she, literally, slipped through his hands ... falling at least 20 feet as a couple of the judges shrieked in horror.

Their only saving grace? 'AGT' airs on network TV -- there's no way they'd allow that kinda stunt without a safety net. Mary, whose mom and young son were watching in the audience, is totally fine.
