Experiments

Volcano

Use bicarbonate of soda and vinegar to get a fizzing chemical reaction ! Equipment: bicarbonate of soda, vinegar, washing up liquid, small container like a plastic bottle or yoghurt pot (optional: plasticine, red food colouring)

Get container

Get a container for your volcano - the smaller the container the less soda and vinegar you'll need for it to spill over. This could get messy so you might want to do it outside or on a tray

Create volcano

Before you start adding ingredients you could make your container look like a volcano by getting the kids to build plasticine onto the sides - but this is optional

Get ingredients

Get your container and let the kids add 1 or 2 tablespoons of bicarbonate of soda and about a teaspoon of washing up liquid. Add red food colouring if you want red lava

The eruption

This is the exciting part! Pour vinegar into the container and watch everything fizz and bubble up over the sides of the container like a volcanic eruption!
