If you’re looking for a new and easy activity for your kid, here is an idea how to set up a little funny chemical experiment – fireworks in a jar! Kids are always fascinated with color and fireworks, so I guess that they would be excited to be part of this. You’ll need to fill your jar ¾ of the way full with warm water. Mix 3-4 tablespoons of oil and some drops of different colors of food coloring in a separate bowl with a fork and then gently pour the resulting mixture into the jar. After that just watch what happens and how the colors would mix! Enjoy!
