In our class we have bean doing experiments. Kaitlin and I made an awesome experiment called a lava- lamp we used: oil, water, food colouring and alka seltzer tablets. Steps: We put three thirds the way of oil in a jar the rest with water leaving an inch between the water and the top of the jar. Then we broke the alker seltzer tablets and but the pieces in. This caused the water to rise. Water doesn't mix with oil so when we added the food colouring it mixed with the water because the density's are different and heavier than others.
