Please note that tickets will not be available to purchase on the door.

Explore the wonders of our oceans and learn about the damaging effects of plastic pollution.

This After Hours, as well as the two floors of hands-on exhibits and puzzles for you to get stuck in to, we have:


Lush Cardiff will be talking about their efforts to combat plastic waste, and the science of change with their bath bombs. Plus, make your own Big Blue Bath Bomb or Turtle Jelly Bomb for a small additional charge, and see their latest fantastic products.
Please note: The Lush pop-up shop and bath bomb activity will be cash only.

Eco Lounge & Ooho

Relax in Cardiff Harbour Authority’s Bay Eco Lounge, plus make a sea-friendly pledge and enjoy an innovative Ooho cocktail with edible packaging!

Keep Wales Tidy

Get involved in a nurdle hunt, a beach clean activity, and find out how you can become a litter champion with Keep Wales Tidy.


Cardiff University will be talking about Sea4All, the project to enhancing critical thinking in schools for marine pollution using innovative ICT technologies.


Cardiff’s first not-for-profit zero waste store, Ripple, will have a pop-up shop showcasing the perfect items to get started with going waste-free.
Please note: The Ripple pop-up shop will be cash only.


Refill Cymru will be talking about their campaign which is trying to stop millions of plastic bottles at source and prevent plastic pollution by making reusing a bottle simpler than buying a new one. Find out how to become a Local Refill Champion and start Refilling your community.

And that’s not all…

Hit the waves and test your skills of balance on our surfboard, and see how long you can stay upright before the inevitable wipe-out!
Feeling thirsty or peckish? We’ve got you covered. There’ll be a fully-licensed bar and street food available on the night.

A glass of Prosecco upon arrival is included in your entry ticket. A non-alcoholic alternative is also available.

Ticket price includes all additional activities — there are no additional fees on the night (except for food and drink purchases, and the Lush bath bomb making activities.)

This event has sold out.

Additional activities have limited availability, and are delivered on a first-come, first-served basis.
