Sometimes they have those spinning tunnels at carnivals where you try to walk through without falling.  But this is WAY more badass.

 

 

Someone recorded their three-year-old daughter doing it.  But instead of walking through, she sat down and just held on to the side.  And apparently she has quite a grip, because she managed to hang on until she was completely UPSIDE DOWN.

 

 

Then she finally fell after she'd almost gone the entire way around.  But she was fine, and even told her mom she really LIKED it. (Search for "My Three-Year-Old's Amazing Death Grip."  She starts at :19.)
