An American Youtuber attempted to become a human water bomb by climbing into a giant water balloon as it filled with water, while inside a boat in a swimming pool.

The silly stunt may have cost the prankster his life, as he began to sink! Luckily, he was not alone and one crew member jumped into the pool with a screwdriver to pop the balloon. Tenny, the balloon man, didn¡¯t seem too fazed by the experience. His video went viral.

Difficult words: attempt (try), stunt (something dangerous), prankster (a person who plays pranks – practical jokes), fazed (shocked or scared), viral (very popular).
