💫Spinning coin inside a balloon experiment. 🌀Experiment on centripetal force.
- The coin was set in motion by the initial force provided by the rotation of the balloon, and the shape of the balloon helps the movement of the coin to a circular path. - There is also a slight friction force between the edge of the balloon and the coin, which slowly helps in stopping the balloon from spinning. - Another force is that of gravity, which pulls down the coin. - But the force which helps the balloon spin into circles is centripetal force. 🧪Materials required- 1. A Coin • 2. A Balloon

Amazing 9 Layer Density Tower! Density differences cause objects to “float” in liquids that are already stacked on top of each other.
