Instructions
1. Spread your hands as far apart as you can along the broom.
2. Pick up the broom using only one finger of each hand... it'll be heavy on the broom end
3. Slowly slide you fingers together at the same speed.
4. You will find that the finger close to the broom head doesn't move much compared to other finger.
5. Once you get you fingers together you have found the broom's center of gravity.
6. Can you balance the whole broom using one finger on that point?
Try other odd shaped objects, e.g. baseball bats, golf clubs and hockey sticks... be careful!
7. Try repeating the experiment, only placing you hands in a different spot.
Do you find the center of gravity each time no matter what?
