Getting Iron from Breakfast Cereal

Did you know you can get iron back out of fortified breakfast cereal?

My son got a chunk of iron from his breakfast cereal.

By crushing breakfast cereal into fine grains,

 adding water,

 and pouring the concoction into a plastic bag,

then dragging a strong magnet, iron can be collected. The dark spot in the upper left hand corner of the bag is a small glob of iron.

This video shows the entire procedure.

Thanks to Lucinda at Navigating by Joy for the idea for this cool science experiment. Once I mentioned it to my son, he was immediately working on getting iron.
