Work combining coco plants, sugar beet, maize and willow trees to create chocolate biscuit bars looked like coming to failure until a minor industrial accident led to our test field being flooded with aluminium oxide.

Problems with the chocolate coating melting on the fully developed bars had led us to try many solutions including spraying with silver paint but this proved cost ineffective.

The aluminium oxide flood however had an unexpected effect, the trees absorbed the aluminium and protectively wrapped their fruit. We are currently researching the exact time that the field needs to be flooded to re-create this effect.
