Christian Wedoy is an escape artist with lungs of steel. Or maybe rubber? Titanium? I don’t really know, but his ability to hold his breath underwater really does seem superhuman. Here he’s showing off his skills with a few goldfish for company, but he can also stay cool underwater for four whole minutes while navigating several layers of locks and chains.

If you’re like me and escape artists make you deeply uncomfortable, then you might want to skip this story. If you can be cavalier watching somebody hold their breath underwater for a whopping 5 minutes while picking the locks restraining him, then by all means marvel at the wild amount of physical control on display by Christian Wedoy. Gulp.

Being an escape artist requires a ridiculous amount of physical training, especially when we’re talking about strapping on handcuffs and plunging into a tank full of water. But as Kristin Johnson (aka Lady Houdini) points out in the video above, there’s definitely a psychological aspect to performing the death-defying feats she does on a routine basis. The London Free Press spoke with Johnson at the Western Fair in Canada back in September and just recently posted their interview on YouTube. She talks about the amount of work that goes into performing an escape, and the importance of staying calm under extreme danger. Check out the interview above, and visit Johnson’s website for more information on when and where she’s performing next.
