There's a great little magic stall in Covent Garden called Magic Cave. Holborn station is just minutes away from there, which is minutes away from International Magic shop! Go there if you can. Fantastic place.
Just a suggestion for those who are unable to redownload the trick Ollie, you could upload the handlings to YouTube and make it an unlisted video, sending the link to those who wish to watch it (me, me, me, me, me).
