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 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
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 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
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!
