🔬⚡ Zinc vs Copper Sulphate! ⚡🔬
Watch how zinc displaces copper from copper sulphate solution in this fascinating displacement reaction. As the reaction proceeds, the blue CuSO₄ solution gradually loses its color while a reddish-brown layer of copper forms on the zinc surface.
Chemical Equation: Zn + CuSO₄ → ZnSO₄ + Cu
Can you explain why zinc is able to replace copper? Let us know in the comments! 👇

🌋✨ Lava Lamp Experiment ✨🌋
Watch science come alive with this colorful lava lamp experiment! Using only oil, water, food color, baking soda, and vinegar, we can create mesmerizing bubbles that rise and fall like a real lava lamp.
🔬 Science Behind It:
Water and oil do not mix because they have different densities. When vinegar reacts with baking soda, carbon dioxide gas is produced. These bubbles carry colored water upward through the oil. As the gas escapes, the water sinks back down, creating the beautiful lava lamp effect.
Try it yourself and explore the amazing world of chemistry!
