You will need:
- Small plastic drinking bottle
- Brown modelling clay
- Bicarbonate of Soda
- White vinegar
- Plastic container
- Washing up liquid
- Red food colouring
Remember to ask a Grown-up for help.
What to do:
Take the plastic bottle and use the modelling clay to make a cone shape around it.
Use more modelling clay at the bottom than the top to make the volcano shape.
You can make it bumpy so it looks like rock.
Put your volcano onto a tray.
Add a small squirt of washing up liquid (about 2 tablespoons), 1 table spoon of red or orange food colouring and 2 tablespoons of bicarbonate of soda.
Finally pour in the vinegar and watch your volcano erupt!
Afterwards, you can wash your volcano and make it erupt again and again.
