The theme sees the festival imagine what the world would be like if we lived underwater and as part of this, Reading’s Global Café will present its take on the topic while a children’s procession at 5.30pm will feature a large crustacean created by their own hands. It will be inspired by H G Wells’ War Of The Worlds.

There will also be a special performance by Sound Interventions, who will present Drift, an outdoor show which imagines, in an abstract way, what our environmental crimes might soon be doing to planet earth.
