Today we made our own model volcanoes and did an experiment to make them erupt.

We built our models from old plastic cups/ tubs and created a volcano from foil. Next we painted our volcanoes.

For the experiment we mixed 2 tablespoons of bicarbonate of soda with 1 cup of vinegar and some red food colouring.  We watched as the mixture bubbled, grew and spilled over the volcano just like lava.
