Step into a world of shimmering, floating, and spectacular soap bubbles at Experimentarium’s Soap Bubble Festival!

During Easter, Ascension Day, and Pentecost, Experimentarium transforms into a magical bubble universe filled with hands-on activities, stunning shows, and bubbly experiences for all ages.

A festival full of bubbles

Get ready for giant bubbles, tiny bubbles, bubbles inside bubbles – even square and explosive bubbles. You can create bubbles, experiment with them, and even step inside one!

Several times a day, we fill the air with cascading bubble rain beneath our iconic copper staircase in the Lobby. Dance, play, and lose yourself in thousands of floating bubbles.

Spectacular shows and bubble tricks

Experience breathtaking bubble shows featuring internationally renowned artists, alongside Experimentarium’s own bubble experts.

Want to master the art yourself? Learn fun and impressive bubble tricks in the Bubblearium and earn your very own bubble diploma.

Soap Bubble artist Pep Bou from Barcelona is part of the Easter program.

Explore, experiment, and create

Bubbles are not just beautiful – they’re science in action!

Discover the fascinating physics behind bubbles. Explore their shapes, colours, and reflections. See what bubbles look like under a microscope and experiment with exciting bubble tools and techniques.

Visit our newly reopened Bubblearium, now expanded to 350 m² with 16 interactive stations packed with creative bubble activities.

Bubbles everywhere

The festival spreads throughout the entire Experimentarium – from the exhibition floors all the way up to our rooftop terrace, where you can create enormous bubbles and watch them drift across the city skyline, sparkling in the sun.

Create bubble art

Turn bubbles into art! Use coloured bubble liquid, let the bubbles burst, and create unique and beautiful artworks together.
