What happens when we put a fizzy tablet in water?

If we mix oil and water can you predict what will happen?

– The oil sits on the top because it is lighter.

*Mathematical Link* – we measured and recorded the amounts of liquid – more oil and less water with colouring resulted in a more impressive lava lamp. Different-shaped bottles were also used to see different effects.
