Kris Sleeman of the Dallas extreme performance group Traumatic Stress Discipline appears to feel no pain. At the 2007 grand opening of the Ripley’s Believe It or Not! Odditorium in San Antonio, Texas, he lay face down in a pile of freshly broken glass bottles, and then invited Ripley employee Viviana Ray to stand on his head. Kris’ pain-defying feats also included having a concrete block on his chest shattered by a sledgehammer while lying on a bed of nails.
Kris Sleeman’s glass act, as featured in Strikingly True, carries a greater potential for injury than many other performances that include glass shards. Most broken glass routines involve walking across glass barefoot or lying with their back to glass, but lying face first adds an extra level of danger. The face is a much less even surface than feet or a back, and that makes cuts more likely.
If you’re interested in his group, the TSD Club, they are a group of suspension practitioners that operate out of Dallas, Texas. When suspending, they run hooks through their flesh and hang freely, supported only by those temporary piercings. The group has been doing this since 1992, has many of the world’s experts in the practice and has worked with Ripley’s to show off their unique talents on a number of occasions.
