The group tutorial (Mon 14th Oct) with Ingrid helped me further think of the possibilities of what I could do with my three objects. One of the ideas for the Art object, is to create a candle of some sort shaped in a coral that melts using a energy source. But instead of using normal electricity, Ingrid suggested to form energy out of algae, which creates more energy, then more algae and so on. Sounds very ambitious, but ideally, it would be perfect for representing one of the many reasons why corals are dying in the ocean; More algae affects the coral due to consuming their sunlight and oxygen.
It sounds very complicated, although I thought it would be a very smart idea if it actually works. There are some websites that tell you how to make energy out of algae at home.
