Rainbow in a Jar

Materials: A tall, see-through container, honey, light corn syrup, dish soap {either blue like Dawn or green like Palmolive} , olive oil, rubbing alcohol, water, food coloring, a dropper 

First pour the honey.  Be sure to pour it into the middle of your container — don’t let it touch the sides.
Next pour in the corn syrup, can color it purple. Again, pour it into the middle of the container, not touching the sides.
Then add the dish soap.
Pour in regular water, can color blue. {If you’re using blue dish soap, obviously color your water something different. Again, in the middle, in the middle!}
The olive oil goes in next. Do you know what I’m going to say? That’s right, pour it in the middle. Also, I recommend pouring a fairly thick layer of oil — it will come in handy for the next step.  Last but not least is the rubbing alcohol. You can color it red— that in itself is a cool peek at different densities because the food coloring just sits at the bottom of the alcohol when you first drop it in. BUT WAIT! DON’T POUR IT IN THE MIDDLE!   This is where the dropper comes in.  If you pour the alcohol straight in, it’ll probably pick up the blue food coloring you used in the water and your rainbow will be ruined.  The best way to add it is dropping the alcohol along the side of the container using a dropper.  The key is not “breaking through” the oil layer into the blue water layer beneath it — that’s why you should put a thick layer of oil.
