Activity Introduction

Let’s make a volcano and then watch it erupt! Spurt lava and enjoy seeing a simple chemical reaction take place.

Safety advice: Red food dye is a very messy ingredient to be using! Use gloves whilst mixing if you would like to keep it off your hands, and ensure that you keep this experiment outside to avoid getting red colouring all over your nice house or apartment. Be careful with mixing sticks to not get them in your eye as they can be pointy.

This is a safe and fun activity for kids to watch and help their parent/caregiver carry out. You will be surprised at how easy it is to do this.

The earth is composed of three layers: the hot metal core in the centre, the red hot mantle surrounding this that is made up of both liquid and solid parts of rock, and the crust which is the cooler outer layer of the earth. Volcanic eruptions happen when pressure builds up in the mantle of the earth, and the magma pushes itself up quickly through the earth’s crust causing an eruption of hot lava. The lava then becomes hard and eventually a mountain is formed around the crack, just waiting for its ne
