WATCH THIS AMAZING BIRD BALANCE ON THE TIP OF YOUR FINGER! YOU'LL KEEP EVERYONE WONDERING HOW!! The center of mass* of any object is the point where the mass of the object is concentrated. If you support an object at its center of mass it will balance—or be in a state of ‘static equilibrium.’ A simple way to find the center of mass of a solid rod or pole is to support the pole horizontally on one finger from each hand. Carefully slide your fingers together, constantly watching the object—moving each finger in such a way as to keep the object level. When your fingers meet, you will be at the center of mass, at which time you can easily hold up the pole with only one finger, as long as it can withstand the entire weight of the pole. Each sold separately. Ships in randomly selected, assorted colours based on availability. Recommended for ages 4+
