To make an erupting volcano you will need a bottle, tray, soil (or sand), bicarbonate of soda, washing-up liquid and vinegar. Red food colouring can also be added to create a more realistic affect! You can then decorate your volcano with plants, stones and toy dinosaurs.
Step 1: Place a bottle on the tray and build a mound of soil around the bottle. Keep the hole open.
Step 2: Mix together the washing – up liquid, bicarbonate of soda and food colouring if using.
Step 3: Place plants, stones and toy dinosaurs around the volcano.
Step 4: Add the vinegar and watch your volcano erupt!
