Would you eat 'Fukushima' soup?

At this year's Frieze Art Fair in London, soup was being cooked and handed out. But this was no ordinary soup. It's an installation by two Japanese artists called The United Brothers, and was made with ingredients from Fukushima. Would you try it?

Frieze week 2014 was marked by the unveiling of a specially commissioned fountain made from garden hoses by artist Bertrand Lavier.

It was the beginning of a week of the bold, the beautiful, and the downright bonkers. Here, a child climbs out of a huge dice, part of an installation by artist Carsten Holler titled "Gartenkinder".

A visitor inspects a disembodied bath, better known as a sculpture by Oscar Tuazon titled "A Fountain".

There were also, as you might have expected, plenty of controversial works. These two paintings by artist Rob Pruitt are called "Suicide Painting LI" and "Suicide Painting XLVII". They are hanging behind an installation by the same artist titled "Coffee Table / Coke Table".

The biggest names of the art world were represented, including Damien Hirst. His sculpture "Because I Can't Have You I Want You" features many fish on shelves.

This artwork is simply studio "Studio". It was painted by the German artist Thomas Scheibitz, and juxtaposes Futurist lines with Fauvist colors.

Children play with a giant scrabble set as part of Carsten Holler's installation "Gartenkinder", in which he the Gagosian Gallery's stand at Frieze was transformed into a children's playground.

The artist Angus Fairhurst exhibited "The Birth of Consistency", a strikingly sinewy and troubling work.

Thomas Demand's Japanese-inspired "Hanami" was one of the most floral works on display, which made it the perfect backdrop for a selfie, apparently.

The artists Slavs and Tatars exhibited "Tongue Twist Her", which resembles a giant tongue coiled around a spike.

(CNN) -- Soup that is rumored to be radioactive; fish in formaldehyde; 10 people sharing a single silk hat. It could only be Frieze London, one of the world's leading contemporary art fairs.

Frieze opens its doors for the 12th year this week, with 162 galleries from 25 countries rubbing shoulders under a massive new tent designed by Universal Design Studio.

Inspired by the art, and encouraged by the promise of free champagne -- the soup not so much -- I head down to join the fun.
