Comment faire de l'électricité avec du sel ? - Défis Cobayes - France 4

👩‍🔬Try this experiment at home! 👨‍🔬 Materials: A vase filled with water One whole orange One peeled orange A wooden board Instructions: Place both oranges in the water. Enjoy. Explanation: An object's ability to float depends on its density. The less dense the object, the more it floats. The whole orange is heavier than the peeled orange, but it is less dense! Indeed, the orange peel is mainly composed of oils, while the flesh is mainly water. And oil is less dense than water. The orange peel thus acts as a buoy and makes the orange float! Similarly, overweight people float better than thin people because fat is less dense than muscle! Catch the Guinea Pig Challenges Monday through Friday at 7:20 PM on France 4!
