Prep:
1. Pull the 2 m. string through the empty pen tube until a little over a meter passes through the tube.
2. Next, attach the rubber stopper to one end of the string by pulling it about 15 cm through one hole, back through the second and fastening the string to the part that enters the first hole.
3. Measure off 1 meter of the string that enters the first hole.
4. Take the other end of the string and attach a paper clip.
5. Measure off 1 meter of string on the apparatus starting from the rubber stopper and ending at the top of the tube that you slid up to the meter mark.
6. Place a piece of tape securely on the string just underneath the other end of the tube.
Materials:
Centripetal Force Apparatus (Ball point pen tube, string, three 2-holed rubber stopper, butterfly paper clip), 30 metal washers, timer, tape, meter stick.
