Activities | Making a Volcano

We’ve had a few requests for some activities to do with older children. So here we go.. If there’s something you’d like us to feature please do get in touch.

This set of instructions was taken from the RSPB’s book ‘365 outdoor activities you have to try’ which is full of ideas to keep children entertained and asking questions. Find it here.

What you need:

Plastic bottle, tray, water, measuring jug, food dye, washing-up liquid, sand, funnel, bicarbonate of soda, vinegar.


  1. Use the measuring jug to measure how much water the bottle holds. Put the empty bottle on the tray.
  2. Pile moist sand around the bottle. Fill the jug with warm water equal to two-thirds of the bottle. Add two heaped dessertspoons of soda and stir.
  3. Add a spoonful of food dye and washing-up liquid to the jug. Stir. Use the funnel to pour the jug contents into the bottle. Add 100ml of vinegar to the jug. Pour it into the bottle and stand back. The eruption is about to take place.

We had great fun making our volcanoes. However I have to be honest it is over rather quickly, (also tricky to photograph) so you may like to prepare some facts, or questions to go alongside this activity. We talked about the chemical reaction that was happening, and then onto baking and how this is similar.

Have you done any experiments lately?
