How to make your own exploding volcano

This was from our ‘fortunately the milk’ project and I must say if you don’t mind the smell of vinegar for a bit it’s well worth doing as kids love it.
You will need:
  • a small pot,
  • a tray, 
  • some playdough, 
  • 100ml of white vinegar coloured red with food colouring 
  • two teaspoons of bicarbonate of soda.
Mould your playdough around the small pot to create a volcano shape and place on your tray.
We added dinosaurs to our tray, Professor Stegs friends are about to meet a horrible end!
Place two teaspoons of bicarb in the pot.
Pour on the vinegar
Watch the volcano erupt and bring an end to the dinosaur population.
Open a window or do this outdoors as the vinegar reaction can be a bit smelly.
