Flour Bomb

I went into Oxford city centre today, and was pelted with a flour bomb. By accident of course, the people who threw it were aiming at some people on bikes as they came out of their graduation ceremony (I think it's tradition to flour bomb/throw confetti/make a mess at Oxford University graduations). I got the majority off of my clothes but some still remained on my shoes, and as far as I'm aware, it's still there! It's interesting observing the many traditions this city has to offer. I saw loads of Oxford Students covered head to toe in flour today! Makes me glad I go to the 'other' university!
