About 45 minutes in the reef, swimming alongside everyone else in the water — and a live audience in Belfast.

Live support on the night

We’re in the Discord while the show runs. If anything breaks, we’re there — and pressing Enter takes you back to the performer if you get lost.

You'll be in the water at the same time as the live audience in Belfast — see the Belfast International Arts Festival show you're joining.
