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.
Place a bottle on the tray and build a mound of soil around the bottle. Keep the hole open.
Mix together the washing – up liquid, bicarbonate of soda and food colouring if using.
Place plants, stones and toy dinosaurs around the volcano.
Add the vinegar and watch your volcano erupt!
