Crash Safari dot com -- and no, I'm deliberately not linking to it! -- crashes your phone. Or your browser. Pretty much instantly. How? And after several months of obscurity, why did it go viral so fast today? And yes, I did have to put this video together really quickly. Thank you SO MUCH to the wonderful Matthew Walster, @dotwaffle on Twitter, who not only found me somewhere to film at short notice but also volunteered to hold the camera. I am massively grateful to him -- thank you!
