Let’s Do A Magic Of Defying Gravity: The Science On How Human Balance On A Tightrope

Balancing is a profession of some people in circus. Today we will reveal to you what is behind balancing on a tightrope. IN this video strip balancing spoon and fork using toothpick alone. Furthermore, to balance you need to find the center of gravity. Gravity is a force that attracts a body toward the center of the earth or toward any other physical objects having mass. The center of gravity is the average location of the weight of an object. The point which balances the object from left to right. front and back or top to bottom. To do this magic trick we need to prepare materials such as a glass, fork, spoon toothpick and lighter.

  1. Put the spoon and fork together.

  3. Use your finger to find the center between spoon and fork to balance.

  5. After finding the center of balance, transfer the attach spoon and fork on the rim of the glass.

  7. Placing the object, the toothpick must be rest horizontally on the rim of the glass. Just slide the toothpick back and forth until you found the exact balancing point. Slightly pull your hands away to reveal the experiment.

  9. Light the toothpick on both ends. And see the changes.

The secret to balance is finding the center of gravity to hold the object equally. The toothpick balance the spoon and fork like your arms when you stand on a rope. If you observe walking on a thin line of rope to balance, your body has principles to be flexible on purpose where gravity pulls down on the pole and helps the walker lower their center on gravity even further by distributing the weight laterally. The center of gravity is directly below the spot where the toothpick rests on the rim of the glass. Looking closely,we can see that the fork handles are positioned below the toothpick. For instance, circus tightrope walker use a pole or stick for balancing. To keep the acrobats steady walking on slackline, they must be responsive to move due to constant movement of rope. Science magazine published a study which researchers reveal the science behind balancing on tightrope. They create a model of a person on a rope with masses, angles and velocities to explain how a person and rope work together.


The found out, a person use its sensory systems alerting the body start to teeter includes eyes, organs of inner ears and orientation information of ankles and knees. They suggest that rapid information about falling provided by the inner ear is sufficient to help rope walkers maintain balance. The researchers discovered the key feature affect balancing is the rope’s sag. When a rope sag a little makes a quicker vibrations, whereas a loose rope of a sag makes larger back-and-forth swing motion.
