Our children have become very interested in doing experiments this year and one of their favourites was when they were science wizards, making a fizzy potion. They listened carefully to instructions as they measured vinegar and washing-up liquid in to a jar. As with all good potion mixing, they children had to give it a good stir and a few magic words before adding baking soda to produce an exciting fizzy fountain. As you can imagine, we had to try this out several times and used different quantities of ingredients each time, including some food colouring, to observe what happened. Science is such fun!
