L’ou com Balla (catalan) – El Huevo como Baila (Spanish) from May 31st. to June 3th., is a tradition in Barcelona over 600 years, and was considered the biggest festival in the city. This curious event is celebrated in different places of Barcelona once in a year.
How can they dance?
Basically an egg that is emptied and plugged with wax in the hole, then is placed in the jet fountain, so that it rotates without falling, or if it falls to the bottom, where it’s picked up again by the water pressure. The fountains are decorated with flowers and fruits.
