I want to do an experiment with my son. We think that we should be able to get a rock with lots of iron in 
it and add something (water?) to make it drip 'blood'. Alternatively, we had the idea of dipping it in a ph 
indicator solution and then adding lemonjuice. What do you think? Is there a more scientific or better way?
