For families enjoying London getaways next weekend, the Diamond Jubilee Festival in Battersea Park will be a big hit with its live music, market stalls and pop-up pubs.
But one particular attraction at the event looks set to be very popular with the crowds. Organisers will be staging a cake contest and the entries are expected to be extremely impressive.
One is a scaled down edible version of the City of London's iconic office block 30 St Mary Axe, which is also known as the Gherkin and is 180 metres tall.
Arup, the company that designed it, is taking on three other teams on Sunday June 3rd in a cake baking contest to celebrate Queen Elizabeth's 60th year on the throne.
Their sweet treat will be two storeys high and will contain a number of key ingredients, all designed to ensure that the mighty cake is sturdy enough to stand up.
"While we know a lot about concrete and steel, we were dealing with things like chocolate and fruit cake," electrical engineer Stephanie Black told the Sunday Times.
"We had to do a lot of testing on the new materials before we realised that diamond-shaped blocks of crispy cakes were the most sturdy."
But Arup will face some tough competition. Also entering the contest will be Expedition Engineering – the company that designed the velodrome for the London Olympics – and engineering firm Buro Happold, which was responsible for building the O2 Arena.
Visitors to Battersea Park won't just be able to view the impressive entries, they will also be invited to taste them once the judging panel have picked a winner.
Other events taking place at the festival include a 1952-themed tea dance, a classic car boot sale, a steam fair featuring nostalgic fairground rides and of course the Thames Diamond Jubilee Pageant.
