I have no idea how this chap pulled off this magic trick, even after watching it about 50 times, but unless he's used some sort of CGI or pre-upload doctoring to do it, how on Earth does the kid magically appear and then disappear in the shirt? This is what Vine was made for. Amazing.
And if anyone can tell me how it's done, fire away down in the comments. I'm guessing all is not what it seems and that the video is altered before uploading to Vine, but maybe it's just magic. Brilliant, either way. [Vine via UsVsTh3m]
