Debt clock

A debt clock is a tool used by governments and news outlets to show how much money a country owes. It works like a clock, except instead of showing the time, it shows the amount of money that is owed. When money is borrowed or spent the debt clock will show the amount that has been added to the total amount of debt. It keeps going up, until the debt is paid off.
