Whether or not this is real (who can tell on the internet?), it’s pretty darn funny.
If I had one billion dollars I would make an orphan believe he was going to Hogwarts to learn magic. I would pay actors to pretend to be wizards and have a fake Hagrid take him shopping at a pretend Diagon Alley. I would plan elaborate magic illusions to convince him he really was a wizard. Finally, I would convince him to run at the wall to get to Platform 9 3/4. As soon as he hits the wall balloons would fall from the sky and a giant banner would fall down and read “Magic Isn’t Real”.
