EXTRACT IRON FROM CEREAL
YOU WILL NEED:
An iron-fortified breakfast cereal (make sure it’s light in colour so you can see the iron – we used a crisped rice cereal and a multigrain cereal)
Rare earth magnet (these are extremely strong magnets, usually made from neodymium)
A large, sealable transparent food bag (a zip-lock style bag is ideal)
A rolling pin and clean surface
