This will be the top Put the top cup on another cup (the base cup).And tape then. Place a third cup next to the base. The third cup is called the bottom cup. Step 2: Pour the water into the top cup while covering the hole with your finger. Start a timer as you uncover the hole. Water will flow into the bottom cup. Step 3: When your timer reaches I minute, quickly draw a line on the bottom cup to mark the top of the water. Make a line every minute. The water will flow slowly as the cup empties. Stop timing when the stream is just a drip. Step 4: Number your marks, starting with "1" from the lowest line. Empty the bottom cup and repeat steps 2-3. Check your marks against the timer. Correct them if necessary.
