SCIENCE EXPERIMENTS : Rainbow in a Bottle || Keith's Toy Box

It's time for another science experiment! Today we're making a rainbow in a bottle. For this experiment, we're going to need a glass bottle, some water, blue dish soap, cooking oil, some honey, rubbing alcohol, red, green and purple food coloring, and a mixing bowl. First you need to pour some honey into the bottle. Then put a few drops of purple food coloring. If you don't have purple food coloring, you can mix red and blue. Because red and blue makes purple! Then mix it well. Next we take our blue dish washing liquid and pour it into the bottle very slowly along the side. We'll take some water. Now we need a little bit of green food coloring. And mix well. Then we pour it into the bottle and again very slowly along the side. Next up is color yellow. This is where you use your cooking oil. Since it's already yellow, we can put it directly. This time we're going to use rubbing alcohol and put some red food coloring. Mix, mix, mix! Now we pour it again into our rainbow. Because each of the liquids have different densities so they don't mix. That's so cool! So that's a rainbow in a bottle! Bye!
