2 paper cups
1. On an upside down paper cup, label “Time Coffee Was Brewed.” Add an arrow pointing to the bottom of the cup.
2. Create a clock around the rim of a second cup. Draw 24 equally spaced lines around the rim of the cup and number them with the hours of the day.
3. Place the first cup on top of the second.
4. When you make a new pot of coffee, rotate the arrow to the time on the clock.
