How to spread fear and demonize sharks

The video below is a prank. I understand that, but what bothers me is how this joke will affect the “marks”(those not in on the prank). The kids in the beginning look mortified. Even though they eventually find out it’s a prank, do you really ever think they will forget what it felt like when they thought a shark killed a human? I don’t. I bet the next time they go to the beach, they will wonder if something is lurking out in the waves waiting to kill them? Agree or disagree share your thought in the comments.
