It's supposed to look like fireworks in a jar. It did look really neat, but not like fireworks. First you put some water in a jar. Then you put some oil in another container and drop food coloring into it. Explain to the kids why the food coloring doesn't mix with oil then pour it into the water. The food coloring then slowly makes it way to the water. At the end of our experiment we also added an alka-seltzer tablet to make a little lava lamp.
