Radioactive atom decay in time in the first exp law that comes to mind. Any

I would for all sakes demonstrate how insurance companies and
governements eat up your savings. Create a savings account for a
newborn child, pay each month a certain amount, increase that monthly
amount every year, as the insurance companies actually do, consider
inflation and interest rates, and then show what miniscule value the
child will get back for consuming as pension when he is > 66.
