The New Scientists playing with food

Two experiments from the New Scientist book ‘How to Fossilise Your Hamster‘.

In the first, we find out how to extract iron from breakfast cereal (perhaps we could use it to make a hammer to deal with the presenter):

In the second, we see how to extract casein (as an example of a polymer) from milk, using just vinegar and a stove. They keep saying ‘plastic’ here, but I’m pretty sure it’s not a plastic. Plastics are polymers, but casein is a protein (though still a polymer). Correct me if I’m wrong. Either way, it might be a good trick to introduce the proteins topics in DP Bio.
