materials
1 glass jar
Honey
Liquid dishwashing liquid soap
Olive oil
Water
Alcohol
Food coloring
1 dropper
Instructions
First pour the honey into the glass jar (without touching the sides) and then add the green dishwashing liquid soap. Then mix water with food coloring (blue or purple, for example) and pour it over the dishwasher taking care not to touch the sides. Continue adding a thick layer of olive oil always in the center of the container.
Finally, mix alcohol with red food coloring, but be careful! Do not pour it in the center like the previous ones. If you do, alcohol can get through the oil layer and reach the layer of water dyed blue or purple, and your rainbow will break down. To avoid this, use a dropper to let the alcohol drain inside the pot.
Explanation
The explanation of this experiment is very simple, the key lies in the density of different liquids. The denser liquids weigh more, and therefore remain at the bottom, and the lightest remain at the top. In addition, having different density, the liquids do not mix and in this way this beautiful rainbow is created.
