Science

Today for science we did three experiments again, and my favourite was the one called lava lamp. We used Berocca tablets, a small fizzy bottle, some oil, and some water, plus food coloring.
First we poured the water into the bottle. Then we poured the oil in, and when we did that it started to sink but then got pushed back up. Then we added the food coloring and it sank through the oil to the water and started to mix, but that changed when we added the Berocca tablets. It started to react with the water causing the food coloring to be lifted up in droplets to the oil which gave a lava lamp like effect. It was really fun.
