Activates the reed switch (shown below) at a distance of about 2cm.

Hold small children to a fridge? Are you sure that's right? o_O

Disclaimer: SparkFun does not endorse nor condone pinning children or small animals to a fridge with magnets.
And for the love of God don't put these up your nose either.
