Materials
  • Sand
  • Tray or wide based bowl (you could also use the sand pit or the ground)
  • Red food colouring
  • Bicarb soda
  • White vinegar
  • A small container

  • Method





  • Scoop sand onto your tray, and shape into a volcano shape.
  • Press your small container into the top.
  • Pour some red food colouring into the container
  • Sprinkle in plenty of bicarb soda

  • Now's the fun part, make sure everyone is ready to witness the eruption of the volcano, and slowly pour the vinegar into the top of the volcano.





  • The volcano will continue to erupt several times if you let the froth settle between pouring in more vinegar, this allows for all children to have a turn. Add more bicarb to keep the the volcano active.
