Brunel Class Lava Lamps

Having earnt our 100 class points, by upholding our school values, we had a class treat of making our own lava lamps. Each of us choose our own colours and watched what happened as we combined oil and water. Then we added salt and watched as the salt slowly sank through the oil and then dissolved into the water, releasing a bubble of oil to rise back to the surface. We discovered that some colours were better than others and we took home our lava lamps to see if we could add more salt to create more bubbles.
