I bought pH test paper (its really hard to get, couldn't find it for ages). I bought 2 types, one is from 1-12 and the other is between 4-5, which is more accurate. I've also bought a 6 volt light bulb and socket. Maybe I should get a 1.5 volt battery, 6 volts might be too much of a resistance. I've got my hands on a strip of copper, however, I don't know where to get a piece zinc. :(. Does anyone know??
Anyways only need to go Woolies or Coles to the other equipment (food) and need to source my zinc. Should be starting experiment next week.
