Creating a quick and easy volcano at home can be both educational and fun! Here’s how to do it using simple household items.

What You'll Need:

• A small plastic bottle or cup
• Baking soda
• Vinegar
• Food colouring (optional)
• A tray or large plate to contain the mess
• Dish soap (optional, for a foamy effect)

Instructions:

1. Prepare Your Base: Place the plastic bottle or cup in the centre of the tray. This will serve as the volcano's core.

2. Add Baking Soda: Spoon in a couple of tablespoons of baking soda into the bottle. This will be the main ingredient for your eruption.

3. Mix in Dish Soap: If you'd like your eruption to be foamy, add a squirt of dish soap to the baking soda. This helps create a more dramatic effect when the volcano erupts.

4. Add Food Colouring: For a more realistic lava effect, add a few drops of food colouring to the baking soda.

5. Create the Eruption: Now for the exciting part! Pour vinegar into the bottle on top of the baking soda mixture. Step back and watch as your volcano erupts in a bubbly, colourful explosion!

Remember, this is a simple chemical reaction between the baking soda (a base) and the vinegar (an acid), which produces carbon dioxide gas and creates the fizzing eruption. Enjoy your scientific masterpiece!
