Balancing a Yardstick

Balancing a Yardstick

Here's an interesting experiment that involves gravity and balance!Hold a yardstick on your index fingers (i.e. the first finger on each hand) with your arms spread wide apart.
What will happen if you move your right hand towards your left hand? At what point will the yardstick fall?Try it! Only move your right hand (try not to move your left hand), and slowly slide your right index finger along the yardstick until it reaches your left hand. The yardstick will keep shifting so that it remains balanced!
