I consider myself to be wary most of the time but I still fell in this last weekend. And I still have the bruses to prove it...
If you haven't seen it, do not make to smart comments; it is realy long and its easy to get distracted, f ex. when you are leaving the ATM as I was (the crack was approx. 3meters from it)

If you fall into this, you have no business to be in the Tate to start with. Get out and get back to Alton Towers where you belong.

Leave the Tate to those of us who don't want safety bannisters up every staircase, don't want Health and Safety warnings everywhere, don't want barriers guiding our every move (my brain can do that thank you very much). Well behaved children, intelligent, bright, polite and curious - welcome to the Tate. Stupid little idiotic brats with parents who don't control them and have brought them up with no respect for adults or objects - go away.

I was walking round the Tate the other day and overheard a member of staff, on his walkie talkie, reporting that he'd found an earing on the floor. He'd kicked said earing to the side of the gallery but was refusing to pick it up as he didn't have any protective gloves! If staff members can be so ridiculous about a lost earing how on earth can they be expected to guide people around the hazards of this "artwork"?

It's difficult to say what is art and what isn't.. this is NOT art though.... my fav reminder of this is the muppets show.. where one of the little dudes comes out on the stage with a brick and a hammer and starts hitting the brick shouting over and over again.. "it's art, it's art, it's art.." before getting whisked off the stage!! haha

I see it is quite normal now to blame somebody esle for any silly mistakes we make

The Piece is very distinct and only Very stupid or Very Blind people will not notice it and if you have children with you who are not fully under your control, you have no business inside the Tate

I hate this slow but sure Americanizing of the UK.

The "unwary"? If they're unwary, what on earth are they doing in the Tate to begin with then? Art has a lot to do about people's interaction with the piece. If they fall in, so be it - that's their interaction. If they don't mind their children in the presence of it - that's the parent's responsibility. If a silly woman puts her foot in it to see how deep it is, that's her choice to interact with the art directly. Cover it in perspex? Rope it off? Oh for goodness sake, stop this nonsense. It's a crack in the floor. Live with it, and if you can't get over yourself, at least get over the crack.

This is sad on two counts; firstly that anyone could consider this to be art, secondly, that people who see it do not realise that the crack is real and fall down it.
Sureal!

This really made me smile. Just make sure everyone's been forewarned of the 'artistic nature' of this earthquake crack, so they can gush accordingly over its artistic merits eh?

What next though? Well, how about: 'Radiation Leak' . That's the title I'll be giving to my forthcoming masterpiece. The entire gallery will be sprayed inside with Strontium-90 and visitors will be encouraged to marvel at the artistic merits of the piece, while their hair falls out and they collapse on the floor in agony.
