Amy Sharrocks has been giving away free tap water at an East End festival aimed at saving the world from ecological disaster.

She set up her water bar at Whitechapel’s Toynbee Hall where she was demonstrating the liquid stuff that she says is one of the planet’s most valuable resources.

Amy runs a Museum of Water, which holds samples from a holy river in India, a garden bird bath, country well, fish tank, cat’s bowl, burst water main, condensation from a window, rainwater from the streets of Hackney and melted snowballs from January.

The story of her liquid assets is featured in the Two Degrees festival, a collective of artists, anarchists, film-makers, storytellers and writers looking at what’s broken in the world and how to fix it.

Performances at the festival also include a spy thriller with the audience seeking secret documents hidden in dead-drops, an anarchist hosting a daily breakfast browsing the commodity data in the FT for diminishing resources, a talk on reading tree rings and a makeshift choir touring nearby streets with songs.

The Two Degrees Festival at Toynbee Hall Studios in Commercial Street runs until Saturday.
